Assertion : Mixture of benzaldhyde and accetaldehyde in hot alkaline medium gives cinnamaldehyde.
Reason : Benzaldehyde is strong electrophile than acetaldehyde.

Assertion : Benzaldehyde is less reactive towards nucleophilic addition than acetaldehyde. Reason : In benzaldehydes, steric hindrance is more than in acetaldehyde.

Assertion : Benzaldehyde is less reactive towards nucleophilic addition than acetaldehyde. Reason : In benzaldehydes, steric hindrance is more than in acetaldehyde.

MnO_(4)^(-) ions can be reduced in strong alkaline medium to give :

Assertion : Cross Cannizzaro's reaction between methanal and benzaldehyde gives benzyl alcohol and formate ion. Reason : Benzaldehyde does not contain a-hydrogen atom.

Assertion : Benzaldehyde is less reactive than propanal towards nucleophilic addition reactions. Reason : Benzaldehyde is less sterically hindred.

Assertion In alkaline medium, H_2O_2 reacts with potassium ferricyanide. Reason H_2O_2 is a strong reducing agent.
