Question

Which of the following will have $s{p}^2$ hybridisation?

• A. $C_2{H}_2$
• B. $C_2{H}_4$
• C. $C_2{H}_6$
• D. $CHC{l}_3$

Answer 1

The correct option is B $C_2{H}_4$

In $C_2{H}_2$ , one carbon is attached to one hydrogen , so it is $sp$ hybridised.


In $C_2{H}_4$ , each carbon is attached to two hydrogen atoms so carbon is $s{p}^2$ hybridised.

In $C_2{H}_6$ , each carbon is attached to three hydrogen atoms so carbon is $s{p}^3$ hybridised



In $CHC{l}_3$ , each carbon is attached to three hydrogen atoms so carbon is $s{p}^3$ hybridised
