(C) The chemical formula for but-$1$-ene is $CH_2=CH-CH_2-CH_3$.To find the number of sigma $(\sigma)$ bonds,we count the bonds in the structure:$1$. $C=C$ bond contains $1$ $\sigma$ bond and $1$ $\pi$ bond.$2$. $C-C$ single bonds: $2$ bonds.$3$. $C-H$ bonds: $2$ (on $C_1$) + $1$ (on $C_2$) + $2$ (on $C_3$) + $3$ (on $C_4$) = $8$ $\sigma$ bonds.Total $\sigma$ bonds = $1$ (from $C=C$) + $2$ (from $C-C$) + $8$ (from $C-H$) = $11$ $\sigma$ bonds.
