Answer 1

e) second reaction undergo reaction by SN1 order mechanism where Br is replace by OH of water forming 3deg. Alcohol. Whereas the first reaction will be slower by SN1 mechanism

f) oxygen has more affinity and reactivity than S so 1st reaction is more stable.

g) here Alcohol react easily with acidic hydrogen bromide but it do not react with non acidic bromide so reaction 1 will only react under acidic catalyst whereas reaction 2 is feasible

h) Here Ch3OH is bulky so it undergo reaction with 3deg. Slower than 2deg. Hence reaction 1 is faster.

i) in reaction 2 CH3 group create hinderance while raction with HS- but in reaction 1 no hinderance is there so reaction one will be faster.
