# What is the bond angle in a chair conformer?

Oct 8, 2015

${109.5}^{\circ}$

#### Explanation:

The bond angle in chair conformation is ${109.5}^{\circ}$ 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.
