Question

How many sigma($\sigma$) and pi($\pi$) bonds does a molecule of $C_2{H}_2$ possess?

• A. $\sigma =6,\pi =0$
• B. $\sigma =2,\pi =3$
• C. $\sigma =3,\pi =2$
• D. $\sigma =4,\pi =1$

Answer 1

The correct option is C $\sigma =3,\pi =2$

$3\sigma$ bonds: $2C-H$ and $1C-C$

$2\pi$ bonds: $2C-C$
