Explanation / Answer
answer for 1
Cumulated Dienes are two double bond connected to a similar atom means consecutively two double bond will come without involvement of any other bond in between.
Example- compound no- II
Conjugated dienes are two double bonds separated by a single bond.
Example- compound no - I , III, IV
Isolated dienes are two double bonds , separated by more than one single bond.
Example- compound no - V
