Question : 7

Total: 36

Two carbon compounds X and Y have the molecular formula C4H8 and C5H12 respectively. Which one of these is most likely to show addition reaction ? Justify your answer. Also give the chemical equation to explain the process of addition reaction in this case.

Solution:

X=C4H8 is an alkene.
Y=C5H12 is an alkane.
X being an alkene i.e., butene is unsaturated compound and will show addition reaction as they have free electrons for bonding.
