Theories of Covalent Bond Formation

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

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

Given below are two statements :

Statement I : ${\mathrm{SO}}_2$ and ${\mathrm{H}}_2\mathrm{O}$ both possess V-shaped structure

Statement II : The bond angle of ${\mathrm{SO}}_2$ is less than that of ${\mathrm{H}}_2\mathrm{O}$.

In the light of the above statements, choose the most appropriate answer from the options given below:

Statement 1: ${\mathrm{SO}}_{2 }\mathrm{and} {\mathrm{H}}_2\mathrm{O}$ both have bent structures.

Statement 2: ${\mathrm{SO}}_2$ have less angle than ${\mathrm{H}}_2\mathrm{O}$.

The correct order of the bond angles in ${\mathrm{NH}}_3,{\mathrm{NH}}_4^{+}$ and ${\mathrm{NH}}_2^{-}$ 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.
