Question:medium

Choose the incorrect statement.

Show Hint

Boiling points increase with the strength of intermolecular forces. Alcohols tend to have higher boiling points than aldehydes and ethers due to hydrogen bonding.

The increasing order of boiling points of 5 compounds having comparable molar masses is as follows: Methoxyethane \( < \) Propanone \( < \) Propanal \( < \) Propan-1-ol
During nucleophilic addition of HCN to RCHO, the hybridisation changes from sp\(^2\) to sp\(^3\) and a tetrahedral intermediate is formed.
Acetone undergoes Wolff Kishner reaction to yield Propane.
The order of reactivity towards nucleophilic attack is Methanal \( > \) Di-tert.butyl ketone \( > \) Benzaldehyde \( > \) Acetophenone.
