Question

Out of CH₃OCH₃, CH₃OH, and H ₂O, which has the largest bond angle and which has the smallest?

1) CH₃OCH₃ has the largest bond angle and H ₂O has the smallest bond angle.
2) CH₃OH has the largest bond angle and CH₃OCH₃ has the smallest bond angle.
3) H ₂O has the largest bond angle and CH₃OH has the smallest bond angle.
4) H ₂O has the largest bond angle and CH₃OCH₃ has the smallest bond angle.

Answer 1

H₉O has the largest bond angle and CH₃OCH₃ has the smallest bond angle.

Step-by-step explanation:

The largest bond angle is found in CH₃OCH₃, while the smallest bond angle is found in H₉O. CH₃OCH₃ has a larger bond angle because it has a tetrahedral molecular geometry, with bond angles close to the predicted 109.5˚ angle. H₉O, on the other hand, has a bent molecular geometry with a bond angle of 104.5˚. Therefore, option 4) H₉O has the largest bond angle and CH₃OCH₃ has the smallest bond angle is correct.
