STANDARD Chemistry Structure and Bonding MCQ Question
The C – O – H bond angle in alcohols is slightly less than the tetrahedral angle whereas the C – O – C bond angle in ether is slightly greater because
repulsion between the unshared electrons pairs of oxygen.
O atom in both alcohols and ethers is sp³-hybridised.
lone pair-lone pair repulsion is greater than bond pair-bond pair repulsion.
None of these.
Correct Answer
Detailed Explanation
In alcohols, the presence of hydrogen bonding reduces the bond angle slightly below the tetrahedral angle. In ethers, the repulsion between lone pairs on the oxygen atom increases the bond angle slightly above the tetrahedral angle.
