Question

If $‘X^{\prime }$ is the number of different functional groups in the compound given above, and $‘Y^{\prime }$ is the
double bond equivalence of the same compound, then $X+Y-10$ is:

Answer 1

Compound has 7 different functional groups (i.e. X=7) and double bond unsaturation is 10 (i.e. Y=10).
So, $X+Y-10=7+10-7=7$
