oxidation number of carbon?​

Answer 1

Question:

• In case of $CH_{3}COOH$, the oxidation number of carbon of carboxylic group is :
• (1) -3
• (2)Zero
• (3)+1
• (4)+3

Answer:

$\large\bold\red{(4)\:+3}$

Explanation:

Given,

A compound $CH_{3}COOH$ .

We have to find the oxidation Number of carbon in carboxylic group.

Now,

Removing the alkyl group , i.e., $\bold{CH_{3}}$ from the compound,

We get,

The carboxylic group, i.e, $\bold{COOH}$.

Now,

In carboxylic group,

Let the oxidation number of carbon be x.

And,

Clearly,

The total charge on the carboxylic group is 0.

This is because,

• The compound is formed by Covalent bonds, and on bond breaking or removal of methyl group, it doesn't leaves any charge .

Therefore,

The sum of individual O.N of each atom will result to 0.

But,

We know that,

• O.N of Oxygen (O) = -2
• O.N of Hydrogen (H) = +1

Therefore,

From the above definition,

We get,

$= > x + ( - 2) + ( - 2) + 1 = 0\\ = > x - 2 - 2 + 1 = 0\\ = > x - 3 = 0 \\ = > x = + 3$

Hence,

The oxidation number of carbon in carboxylic Group is Option (4) +3.
