Question

Methanol is the planar molecule like ethene but the bond angle is ${117.3}^o$.This is because:

• A. of carbonyl carbon atom
• B. of carbon oxygen bond
• C. of strain
• D. none of these

Answer 1

Answer: (C)

of strain

In the molecule their occur repulsion between bonding orbitals, to that strain developed in the molecule and to minimize the strain, bond angle changes and in ethanol is becomes ${117.3}^0$.
