Valence Bond Theory

Which of the following plot represents potential energy of a pair of nuclei as a function of their separation:

$\mathrm{Pz}$ and $\mathrm{dyz}$ form which bond at $\mathrm{x}$ axis?

The number of $\sigma$ bonds, $\mathrm{\pi }$ bonds and lone pair of electrons in pyridine, respectively.

Explain valance bond theory.

There are $\mathrm{x}$ number of $\mathrm{\pi }$ bonds and $\mathrm{y}$ number of $\mathrm{\sigma }$ bonds present in the compound given below :

The value of $\frac{\mathrm{x}+\mathrm{y}}{2}$ is

A single bond is always a '$\mathrm{\sigma }$' bond where as multiple bonds contain bolh $\mathrm{\sigma }$ and $\mathrm{\pi }$ bonds. A double bond contains one $\mathrm{\sigma }$ and and one $\mathrm{\pi }$ bond whereas a triple bond contain one $\mathrm{\sigma }$ and $2 \mathrm{\pi }$ bonds. On basis of this statement calculate $\mathrm{\sigma }$ and $\mathrm{\pi }$ bonds in $\mathrm{HC}\equiv \mathrm{C}-\mathrm{CH}={\mathrm{CH}}_3$.

Calculate the number of $\sigma$ and $\pi$ bonds in $2-\mathrm{n}$-propylpent-$1$-ene.
