The logical reason for Chemistry

Higher Secondary is the most important stage of schooling because it is at this point that specialized discipline-based, content-oriented courses are introduced. Students reach this stage after completing ten years of general education and choose Chemistry to pursue a career in basic sciences or professional courses such as medicine, engineering, or technology, as well as tertiary study courses in applied science and technology. As a result, learners must be provided with a sufficient conceptual background in Chemistry in order to be prepared to meet the challenges of academic and professional courses after high school.

Chemistry in Class 11

Chemistry studies the composition, structure, properties, and reactions of matter. Chemistry is included as one of the major disciplines in CBSE class 11 for a variety of reasons.

1. First and foremost, chemistry is essential for understanding the basic structure and composition of matter.
2. In addition, chemistry plays a critical role in many other disciplines, such as biology, environmental science, and engineering.
3. Furthermore, chemistry is a fascinating subject in its own right, and studying it can provide a deeper understanding of the world around us.
4. Finally, chemistry is a practical subject that can be used in everyday life, and it is therefore important for students to have a good understanding of it.

Integrating Case Study Questions in Chemistry for Class 11

Case study questions can be a great way to integrate real-world applications of chemistry into your class 11 curriculum. By posing questions that require students to analyze and apply their knowledge of chemical concepts, you can help them to see how those concepts are relevant to their lives outside of the classroom. Additionally, case study questions can be used to spark lively classroom discussion and debate.

Class 11 Chemistry Case Study Question 1

Read the passage and answer the following question:
In 1830, Michael Faraday showed that if electricity is passed through a solution of an electrolyte, chemical reactions occurred at the electrodes, which resulted in the liberation and deposition of matter at the electrodes. In mid-1850s Faraday began to study electrical discharge in partially evacuated tubes, known as cathode ray discharge tubes.  When sufficiently high voltage is applied across the electrodes, current starts flowing through a stream of particles moving in the tube from the negative electrode to the positive electrode. These were called cathode rays or cathode ray particles. J.J. Thomson measured the ratio of electrical charge (e) to the mass of the electron (m_e) by using a cathode ray tube and applying electrical and magnetic fields perpendicular to each other as well as to the path of electrons. A positively charged particle was characterised in 1919. Later, a need was felt for the presence of an electrically neutral particles as one of the constituents of the atom.

In this question, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices

1. Assertion and reason both are correct statements and reason is the correct explanation for assertion.
2. Assertion and reason both are correct statements and reason is not the correct explanation for assertion.
3. Assertion is the correct statement but reason is wrong statement.
4. Assertion is the wrong statement but reason is correct statement.

   Reason:  In the absence of electrical or magnetic field, cathode rays travel in straight lines.
2. Assertion: Thomas argued that the lighter the particle, greater the deflection.
   Reason: Deflection depends upon the mass of the particle.
3. Assertion: Television picture tubes are anode ray tubes.
   Reason: Electrons are the basic constituent of all the atoms.

Class 11 Chemistry Case Study Question 2

Read the passage and answer the following question:
The existing large number of organic compounds and their ever-increasing numbers has made it necessary to classify them on the basis of their structures. Organic compounds are broadly classified as open-chain compounds which are also called aliphatic compounds. Aliphatic compounds further classified as homocyclic and heterocyclic compounds. Aromatic compounds are special types of compounds. Alicyclic compounds, aromatic compounds may also have heteroatom in the ring. Such compounds are called heterocyclic aromatic compounds. Organic compounds can also be classified on the basis of functional groups, into families or homologous series. The members of a homologous series can be represented by general molecular formula and the successive members differ from each other in molecular formula by a –CH₂ unit.

In these questions, a statement of assertion followed by the statement of reason is given. Choose the correct answer out of the following choices

Class 11 Chemistry Case Study Question 3

Read the passage and answer the following questions:
A large number of orbitals are possible in an atom. Qualitatively these orbitals can be distinguished by their size, shape and orientation. An orbital of smaller size means there is more chance of finding the electron near the nucleus. Similarly, shape and orientation mean that there is more probability of finding the electron along with certain directions than along others. The principal quantum number determines the size and to large extent the energy of the orbital. Azimuthal quantum number, ‘l’ is also known as orbital angular momentum or subsidiary quantum number. It defines the three-dimensional shape of the orbital. Each shell consists of one or more subshells or sub-levels. The number of sub-shells in a principal shell is equal to the value of n. Magnetic orbital quantum number. ‘ml ’ gives information about the spatial orientation of the orbital with respect to a standard set of co-ordinate axis. The fourth quantum number is known as the electron spin quantum number (m_s). An electron spins around its own axis, much in a similar way as the earth spins around its own axis while revolving around the sun.
In these questions, a statement of assertion followed by the statement of reason is given. Choose the correct answer out of the following choices:

1. Assertion and reason both are correct statements and reason is the correct explanation for assertion.
2. Assertion and reason both are correct statements and reason is not the correct explanation for assertion.
3. Assertion is the correct statement but reason is wrong statement.
4. Assertion is the wrong statement but reason is correct statement.

1. Assertion: Each orbital is designated by three quantum numbers labelled as n, l and m_l.
   Reason:  ‘n’ is a positive integer with value of n = 1,2,3.
2. Assertion: The principal quantum number identifies the shell.
   Reason: Size of an orbital decrease with the increase of principal quantum number ‘n’.
3. Assertion: For n = 2, the possible value of l can be 0 and 1.
   Reason: For a given value of n, l can have n values ranging from 0 to n – 1.
4. Assertion: Each orbital in an atom, is defined by a set of values for n, l and m_l.
