Question

Cyclopentadiene is a _______ donor. (a) three (b) two (c) fve (d) one R​

Answer 1

Explanation:

i think two ....

but not confirm

.

Answer 2

Answer:

correct option is c) Five

Explanation:

Maximum number of electrons donated by cyclopentadiene are Five electrons .

1. Two pi bonds are present in cyclopentadiene structure.

These pi bonds are neutral.

Each pi bond donate 2 electrons.

2 pi bond donate 4 electrons.

2. when cyclopentadiene acquires negative charge on it then system becomes Aromatic.

Aromatic system is the most stable system.

This donate 1 electron.

Therefore , cyclopentadiene is a five electrons donor .
