question 4
list the number of sigma bonds and pi bonds in the following compound.
σ - bonds
π - bonds

Explanation:

Step1: Count sigma bonds

A single bond is a sigma bond. A double bond has one sigma bond and a triple bond has one sigma bond.
In the given compound:

• The \(N\equiv C\) triple bond has 1 sigma bond.
• The \(C - C\) single bond has 1 sigma bond.
• The \(C = C\) double bond has 1 sigma bond.
• Each \(C - H\) single bond (there are 3 \(C - H\) bonds) has 1 sigma bond each.

Total sigma bonds: \(1+1 + 1+3=6\)

Step2: Count pi bonds

A double bond has one pi bond and a triple bond has two pi bonds.

• The \(N\equiv C\) triple bond has 2 pi bonds.
• The \(C = C\) double bond has 1 pi bond.

Total pi bonds: \(2 + 1=3\)

Answer:

\(\sigma\)-bonds: \(6\)
\(\pi\)-bonds: \(3\)
