Explanation / Answer

Cannot see images in Q1 and 2.

What is the index of hydrogen deficiency of a compound with a molecular formula of C5H9Br?

index of hydrogen deficiency = [2C + 2 -H -X-N]/2 = {2*5 +2 -9-1}/2 = 1

So, answer b.1

What is the index of hydrogen deficiency of a compound with a molecular formula of C6H7Cl?

index of hydrogen deficiency = [2C + 2 -H -X-N]/2 = {2*6 +2 -7-1}/2 = 3

So, answer d.3
