$C{H}_{2}C{l}_2$

$C{H}_2=C=C{H}_2$

$C{H}_{3}N{O}_2$

Indicate the $\sigma$ and n bonds in the following molecules:

Answer 1

$C_6{H}_6$

There are six C - C sigma $\left({\sigma }_{C-C}\right)$ bonds, six C–H sigma $\left({\sigma }_{C-H}\right)$ bonds, and three C=C pi $\left({\pi }_{C-C}\right)$ resonating bonds in the given compound.

$C_6{H}_{12}$

There are six C - C sigma $\left({\sigma }_{C-C}\right)$ bonds and twelve C–H sigma $\left({\sigma }_{C-H}\right)$ bonds in the given compound.

$C{H}_{2}C{l}_2$

There two C - H sigma $\left({\sigma }_{C-H}\right)$bonds and two C–Cl sigma $\left({\sigma }_{C-Cl}\right)$ bonds in the given compound.

$C{H}_2=C=C{H}_2$

There are two C - C sigma $\left({\sigma }_{C-C}\right)$ bonds, four C–H sigma $\left({\sigma }_{C-H}\right)$ bonds, and two C=C pi $\left({\pi }_{C-C}\right)$ in the given compound.

$C{H}_{3}N{O}_2$

There are three C–H sigma $\left({\sigma }_{C-H}\right)$ bonds, one C–N sigma $\left({\sigma }_{C-N}\right)$ bond, one N–O sigma $\left({\sigma }_{N-O}\right)$ bond, and one N=O pi $\left({\pi }_{N-O}\right)$ bond in the given compound.

$HCONHC{H}_3$

There are two C–N sigma $\left({\sigma }_{C-N}\right)$ bonds, four C–H sigma $\left({\sigma }_{C-H}\right)$ bond, one N–H sigma $\left({\sigma }_{N-H}\right)$ bond, and one C=O pi $\left({\pi }_{C-O}\right)$ bond in the given compound.
