Q4. When the rate of evaporation is equal to the rate of condensation, it is called
Answer : Option D
Explaination / Solution:
At equilibrium, the rate of evaporation is equal to the rate of condensation.
It may be represented by H2O (l) ⇌ H2O (vap)
The double half arrows indicate that the processes in both the directions are going on simultaneously. The mixture of reactants and products in the equilibrium state is called an equilibrium mixture

Answer : Option C
Explaination / Solution:
chemical properties depend on intramolecular bonding forces whereas physical properties depend on intermolecular nonbonding forces
Q6. Glycerol is
Answer : Option C
Explaination / Solution:
Glycerol and trihydroxypropane are common names. The IUPAC name is propane-1,2,3-triol. The common name glycerol comes from the root glyco- which means sweet. Glucose, glycogen, and glycerin (another name for glycerol) have the same etymology.
