Question

Can someone help me write the organic products of these substitution reactions?

Answer 1

Answer:

Explanation:

first see degree of the bromine in each compound if it is 1 degree irrespective of solvent it shows sn2 reaction

if it is 3 degree irrespective of solvent it shows sn1 reaction

if it is 2 degree it is dependent on nature of solvent

let solve now

if you see in first it shows sn2 reaction as solvent polar aprotic

if you see in  second it shows sn1 reaction as solvent is polar protic

third shows sn1 reaction as it is resonance stabilised

if you see in fourth it shows sn2 reaction as solvent is polar aprotic

if you see in fifth it shows sn1 reaction as solvent is polar protic

products=

in first detach br and attach n3

in second first remove br and make hydride shift and attach oac

in third detach br and attach nucelophile

in fourth detach br and attach cn

in fifth detach br and attach oac

in sixth and seventh also detach and attach

in eighth detach bromine and attach c triple bnd c ph
