Question

The number of sp2 – sp2 sigma bonds in the compound given below is :
(1) 1
(2) 3
(3) 4
(4) 5​

Answer 1

Given:

A compound has been given.

To find:

Number of sp²-sp² sigma bonds?

Calculation:

First of all, whenever a carbon-carbon bond is a :

• single bond, carbon is sp³ hybridised.

• double bond, carbon is sp² hybridised.

• triple bond, carbon is sp hybridised.

Now, see the attached diagram to see the sp² hybridised carbon.

So , the total number of sigma bonds (marked in tick marks) comes as:

$3 \: \sigma \: bonds$
