How many and bonds are present between the carbon atoms in 1-butene-3-yne ()? — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

In the carbon chain $C=C-C\equiv C$, there are 3 C-C connections. The double bond has $1\ \sigma$ and $1\ \pi$. The single bond has $1\ \sigma$. The triple bond has $1\ \sigma$ and $2\ \pi$. Therefore, between carbon atoms, there are $3\ \sigma$ and $3\ \pi$ bonds in total.
