The answer should be in the carbonyls chapter, toward the end of the book.

Good luck!

Just break the double bond, ylide/corbonyl for each side = 2 combos... if Im thinking correctly 😉

A Ylide can be viewed as just a carbon carbon double bond. So you just look at the number of double bonds, in this case 1. So there are two ways to form this compound.

#1 having a COH2 and a Ylide looking like this (C6H5)3P-:CHCH3

#2 having CH3COH and a Ylide looking like (C6H5)3P-:CH2

Hope that helps!!
