Question

acrylonitrile, c3h3n, has the lewis structure shown in the figure. the molecule has ______ σ bonds and ______ π bonds.

Answer 1

Acrylonitrile has three sigma (σ) bonds and two pi (π) bonds.

Step-by-step explanation:

The Lewis structure of acrylonitrile, C3H3N, shows that there are three sigma (σ) bonds and two pi (π) bonds.

A sigma (σ) bond is formed by the head-on overlap of atomic orbitals along the bond axis. In acrylonitrile, the sigma (σ) bonds are formed between carbon and hydrogen, carbon and nitrogen, and nitrogen and hydrogen.

A pi (π) bond is formed by the sideways overlap of adjacent p orbitals. In acrylonitrile, the two pi (π) bonds are formed between the carbon and nitrogen atoms.

Answer 2

Acrylonitrile (C3H3N) has one sigma (σ) bond and two pi (π) bonds.

Step-by-step explanation:

The molecule acrylonitrile (C3H3N) has one sigma (σ) bond and two pi (π) bonds.

In the Lewis structure of acrylonitrile, the carbon atom is bonded to three hydrogen atoms and a nitrogen atom. The nitrogen atom is double bonded to one of the carbon atoms, while the other carbon atom is double bonded to an oxygen atom. The sigma bond is formed from the overlap of two atomic orbitals, while the pi bonds result from the overlap of two sets of unhybridized p-orbitals.
