The major product formed in the following reaction is:

Correct answer

0

Step-by-step solution

Note: In the given reaction a molecule of HCl is lost and C = C double bond is formed. Thus it is dehydrohalogenation reaction. Nitro group is electron withdrawing group. Hence increases the acidity of H atom (attached to C atom bearing nitro group) which is removed easily. Further the newly formed double bond is in conjugation with nitro group.
