Reactants and products coexist at equilibrium, so that the conversion of reactant to products is always less than 100%. Equilibrium reaction may involve the decomposition of a covalent (nonpolar) reactant … Read more
Case Study Questions for Class 11 Chemistry Chapter 6 Thermodynamics Case Study Questions Question 1: Read the passage given below and answer the following questions. In chemical thermodynamics, the type of work involved is mostly pressure-volume work that is the work done when a system (gas) expands or contracts against an external opposing pressure. Hence, … Read more
Case Study Questions for Class 11 Chemistry Chapter 11 The p-Block Elements Case Study Questions Question 1: p-block elements are the ones in which the last electron enters in a p-orbital of valence shell. The first members of each group of p-block differs from rest of the members of its corresponding group due to small … Read more
Case Study Questions for Class 11 Chemistry Chapter 13 Hydrocarbons Case Study Questions Question 1: The rotation of carbon-carbon single bond (s-bond), due to cylindrical symmetry of s-MOs (molecular orbitals) long internuclear axis, in alkanes results into different spatial arrangements of atoms in space, that are interconvertible. These arrangements are called conformations. However, weak repulsive … Read more
Case Study Questions for Class 11 Chemistry Chapter 5 States of Matter Question 1: Intermolecular forces are the forces of attraction and repulsion that exist between molecules of a compound. These cause the compound to exist in a certain state of matter – solid, liquid or gas and affect the melting and boiling points of … Read more
Case Study Questions Class 11 Chemistry Chapter 1 Some Basic Concepts of Chemistry Question 1: The identity of a substance is defined not only by the types of atoms or ions it contains, but by the quantity of each type of atom or ion. The experimental approach required the introduction of a new unit for … Read more
