(a) How many you account for the following :
(i) Aldehydes are more reactive than ketones towards nucleophiles.
(ii) The boiling points of aldehydes and ketones are lower than of the corresponding acids.
(iii) The aldehydes and ketones undergo a number of addition reactions.
(i) Acetaldehyde and benzaldehyde
(ii) Propanone and propanol

Why do aldehydes and ketones undergo a number of addition reactions ?

(a) How many you account for the following : (i) Aldehydes are more reactive than ketones towards nucleophiles. (ii) The boiling points of aldehydes and ketones are lower than of the corresponding acids. (iii) The aldehydes and ketones undergo a number of addition reactions. (b) How will you distinguish between these compounds: (i) Acetaldehyde and benzaldehyde (ii) Propanone and propanol

The boiling points of aldehydes and ketones are lower than the corresponding acids and alcohols. Give reason

How would you account for the following: The boiling points of aldehydes and ketones are lower than that of the corresponding acids.

Why do aldehydes and ketones undergo nucleophilic addition reactions. Give one example.

Why are aldehydes more reavtice than ketones towards nucleophilic addition reactions ?

A : Aldehydes and ketones undergo nucleophilic addition reaction. R : Aldehydes and ketones contain carbonyl group.

Boiling points of ketones are higher than those of the isomeric aldehydes. Assign reason.

(a) The double bond in aldehydes and ketones is reactive towards nucleophilic reagents like CN^(-) whereas that in an alkene is not. (b) Alkenes undergo electrophilic addition whereas aldehydes and ketones undergo nucleophilic addition.

How can aromatic aldehydes and ketones be prepared by the following reaction ? (i) Etard reaction.
