Question

If the molecular formula of compound E is $C_x{H}_y{O}_z$. Then, the value of $y-x-z$ is:

Answer 1

Formula of compound D is $C_{10}{H}_{16}$.
Hydration of D results in addition of $H_{2}O$.
Formula of compound E becomes $C_{10}{H}_{18}O$
On comparing with $C_x{H}_y{O}_z$, we get $x=10,y=18,z=1$
Hence, $(y-x-z)=18-10-1=7$
