e) answer : b
Orthochlorophenol is most acidic. Ortho fluorophenol loses its acidity as it forms hydrogen bonds in solution due to which H+ is not freely liberated. Phenol has least acidity because the other two have an electronic withdrawing group but phenol doesn't.
f) answer : c
The second is an allyl free radical which is more stable because of conjugation. The first tertiary free radical is more stable than the third secondary free radical.
g) answer :f
Nucleophilicity increases as we go down the group of the attacking atom. The nucleophilicity of water is the least as it is a neutral atom.
h) answer : a
Br is a better leaving group than OH because it is a better nucleophile. NH3 is a poor leaving group because it is a strong base and attracts the bonded electrons more.
