Q. Acetic acid and $P_{2}O_{5}$ reacts to produce which of the following?
A) Acetic anhydride
B) Acetaldehyde
C) Phosphoric acid
D) Acetone
Explanation
(a)
Acetic acid on dehydration produce acetic anhydride. $P_{2}O_{5}$ is a dehydrating agent it dehydrate $CH_{3}COOH$ to anhydride.
$2CH_{3}COOH\underset{( - H_{2}O)}{\overset{{\ \ P}_{2}O_{5\ \ }}{\rightarrow}\ \ \ }\left( CH_{3}CO \right)_{2}O$
Acetic acid acetic anhydride
