Question

In pyrrole the electron density is maximum on which number atom?

• A. $2$ and $3$
• B. $3$ and $4$
• C. $2$ and $4$
• D. $2$ and $5$

Answer 1

The correct option is D $2$ and $5$

For pyrrole, following resonating structures can be made:

Here, resonating structures $3$ and $4$ are more stable than

$2$ and $5$.

Thus, electron density is maximum on $2^{nd}$ and $5^{\text{th}}$ site.

So, option(D) is correct.
