Order of hydrolysis for the following
(I) `RCOCI" "(II) RCOOR`
(III) `RCONH_(2)" " (IV) (RCO)_(2)R`

Options

A. I `gt` IV `gt` II `gt` III
B. I `gt` II `gt` III `gt` IV
C. I `gt` III `gt` II `gt` IV
D. IV `gt` III `gt` II `gt` I

Answer

A

Explanation

Of all the acid derivatives, acid chlorides i.e., `CH_(3)COCI` is most reactive.
The order of reacitivity of acid derivatives decreased in the following order.
`RCOCI gt (RCO)_(2)O gt RCOOR gt RCONH_(2)`.
