Question #a5716

Answer 1

There are 15 σ and 4 π bonds in a molecule of salicylaldehyde.

Explanation:

The main things to remember are:

• Every bond contains a σ bond
• Every double bond also contains a π bond

The structure of salicylaldehyde is

Note that there are four unshown `"C-H"` bonds on the aromatic ring.

Thus, there are 5 `"C-H"` bonds, 4 `"C-C"` bonds, 1 `"C-O"` bond, 1 `"O-H"` bond, 3 `"C=C"` bonds and 1 `"C=O"` bond.

This makes a total of 15 bonds, so there are 15 σ bonds.

There are 4 double bonds (3 `"C=C"` and 1 `"C=O"`), so there are 4 π bonds.
