Question

What is the bond angle in a chair conformer?

Answer 1

`109.5^@`

Explanation:

The bond angle in chair conformation is `109.5^@` similar to the bond angle in a tetrahedral geometry.

In fact, cyclohexane take the chair conformation to achieve a bond angle similar to the tetrahedral geometry to eliminate angular strain.

Here are videos where I full explain the chair conformation and why it happens, along with its stereoisomerism and energy.
