Question

The order of stability of carbanion is:

• A. $1>2>3$
• B. $2>3>1$
• C. $3>2>1$
• D. none of the above

Answer 1

The correct option is A $1>2>3$

Now the distance between electronegative $O$ atom and negative charge is in order $:1<2<3$. As distance between them increases the stability of carbanion decreases.

Therefore stability of carbanion $:1>2>3$.
