Answer:
Correct Answer: 1. (a)
Solution:
In step-1 dehydrohalogenation reaction takes place. Here, hydrogen is eliminated from $\beta$-carbon and the halogen is lost from $\alpha$-carbon atom. As a result diene is formed.
Cyclohex -1, 3-diene on ozonolysis gives butane-1, 4- dial and ethane- 1, 2- dial.
