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!
