Allyl phenyl ether can be prepared by heating :
Options
- ACH 2 = CH - Br + C 6 H 5 - CH 2 - ONa
- BC 6 H 5 - CH = CH - Br + CH 3 - ONa
- CCH 2 = CH - CH 2 - Br + C 6 H 5 ONa
- DC 6 H 5 Br + CH 2 = CH - CH 2 - ONa
Correct answer
C. CH 2 = CH - CH 2 - Br + C 6 H 5 ONa
Step-by-step solution
It is a Williamson's ether synthesis reaction. It is a S N 2 reaction. Aryl halides will not undergo nucleophilic substitution reactions readily. Hence, allyl-phenyl ether can be prepared by reaction of allyl halide and phenoxide ion as follows
