Polymerization and hydrolysis
Polymerization and condensation
Correct answer is A
No explanation has been provided for this answer.
Geometric isomerism
Positional isomerism
Structural isomerism
Optical isomerism
Correct answer is D
Optical isomers are molecules that are non-superimposable mirror images of each other and they are not identical. Molecules with a chiral carbon show this kind of isomerism. Chiral carbon, also known as asymmetric carbon, refers to carbon atom that are bonded to four different atoms or groups of atoms.
10H+ (aq)

A reversible reaction
A spontenous reaction
An endothermic reaction
An exothermic reaction
Correct answer is D
In salts for which the hydration energy is higher than the lattice energy, solvation occurs with a release of energy in the form of heat. A reaction in which there is a release of energy as LIGHT OR HEAT is EXOTHERMIC.
