Question

In case of $C{H}_{3}COOH$, the oxidation number of carbon of carboxylic group is.

• A. $-3$
• B. Zero
• C. +1
• D. +3

Answer 1

Answer: (D)

$H-\underset{\stackrel{|}{H}}{\stackrel{\underset{|}{H}}{C^0}}-\stackrel{\underset{||}{O^{-2}}}{C}-\underset{-1}{O}-H$
$\therefore x+0-2-1=0$
$\Rightarrow x=+3$
