Explanation / Answer

According to chegg rules we have to answer only first one problem

C6H10

DBE = C - (H/2) – (x/2)+ (N/2) +1

where C = number of carbon atoms, H = number of hydrogen and halogen atoms, and N = number of nitrogen atoms, x= number of halogen atoms

DBE = 6- (10/2) – (0)+ (0) +1

=6-(10/2)-0+0+1

=6 – 5 +1

= 2

Thus this compound has total double bond 2 or and rings 2 or one ring and one double bond or one triple bond.
