**cyclopentanone** is treated with **piperidine** in acid catalyzed conditions to form the organic product (A). (A) on reaction with *benzyl bromide* followed by hydrolysis gives another organic product (B) containing aromatic ring. If the sum of degrees of unsaturation of (A) and (B) is **x** and the difference of the number of carbon atoms in (A) and (B) is **y**, then find the value of x/y.


According to me compound (A) is an enamine, but I'm not sure about (B)!

So according to this, my answer is x/y = 10/7
But the actual answer is **x/y = 4.5**

I don't know where am I going wrong!
