Vedclass · Answer

(A) The number of $\sigma$ and $\pi$ bonds are calculated as follows:$(i)$ Methane $(CH_4)$: It has $4$ $C-H$ single bonds. Total: $4\sigma, 0\pi$.$(ii)$ Ethane $(C_2H_6)$: It has $1$ $C-C$ single bond and $6$ $C-H$ single bonds. Total: $7\sigma, 0\pi$.$(iii)$ Ethene $(C_2H_4)$: It has $1$ $C=C$ double bond $(1\sigma, 1\pi)$ and $4$ $C-H$ single bonds. Total: $5\sigma, 1\pi$.$(iv)$ Ethyne $(C_2H_2)$: It has $1$ $C\equiv C$ triple bond $(1\sigma, 2\pi)$ and $2$ $C-H$ single bonds. Total: $3\sigma, 2\pi$.

Determine the number of sigma $(\sigma)$ and pi $(\pi)$ bonds in the following molecules: $(i)$ Methane,$(ii)$ Ethane,$(iii)$ Ethene,$(iv)$ Ethyne.
