In the following there are three carbon-oxygen bonds denoted by x, y and z.

Electronic Displacement Effect diagram 809 Their lengths are in order

Options:

Answer:

Solution:

The $C = O$ bond x has the greatest bond order and is shortest. Donation of the ester oxygen lone pair gives the acyl $C - O$ bond y partial double-bond character, making it shorter than the ordinary $O - CH_{3}$ single bond z. Thus x < y < z.
