# Why does methane have 4xxC-H bonds?

Because $C {H}_{4}$ is the formula of the methane molecule.......i.e. a carbon nucleus can form up to $4 \times C - H$ bonds......
$\text{Methane}$ is the first of a series of the homologous alkanes, general formula, ${C}_{n} {H}_{2 n + 2}$. The next member is $\text{ethane}$, ${C}_{2} {H}_{6}$, then $\text{propane}$, ${C}_{3} {H}_{8}$........
