In the following reaction which bonds are cleaved?
`CH_(3)CH_(2)-overset(O)overset(||)underset("I")Ooverset(q)overset(darr)-Ooverset(p)overset(darr)-H+CH_(3)CH_(2)overset(s)overset(darr)underset("II")-Ooverset(r)overset(darr)-H`

A

bond p of I and s of II

B

bond q of I and r of II

C

bond p of I and r of II

D

bond q of I and s of II

Text Solution

Verified by Experts

The correct Answer is:
B
`CH_(3)CH_(2)-overset(O)overset(||)C-O-H+CH_(3)CH_(2)-overset(18)O-H`
`" "CH_(3)CH_(2)overset(O)overset(||)C-overset(darr)overset(18)O-CH_(2)CH_(3)+H_(2)O`
If oxygen of `CH_(3)CH_(2)OH` is labelled with `.^(18)O,` then it goes with ester formed, indicating cleavage of bond q in l and r in II.
