Vedclass · Answer

(C) The given molecule is $2$-methylpent-$1$-en-$4$-yne,which has the structure $CH_2=C(CH_3)-CH_2-C\equiv CH$. Counting the bonds: $1$. $\sigma$ bonds: There are $16$ $\sigma$ bonds in total ($1$ in $C=C$,$1$ in $C-C$,$1$ in $C-C$,$1$ in $C\equiv C$,and $12$ $C-H$ bonds). $2$. $\pi$ bonds: There is $1$ $\pi$ bond in the double bond $(C=C)$ and $2$ $\pi$ bonds in the triple bond $(C\equiv C)$,totaling $3$ $\pi$ bonds. Thus,the molecule contains $3 \pi$ and $16 \sigma$ bonds.

How many $\pi$ bonds and $\sigma$ bonds are present in the following molecule?
