ANSWER:

Solution:

Step 1

The structure of allylic halide is,

(a) The  first-order ionization of an allylic halide and the resonance stabilization is given below-

In this 1st order ionization process, the halide group (X), from the allyl halide has been released as X- ion and forms a carbocation. This carbocation has two resonance structures.
