Question

If ‘x’ ml of butan-1amine and ‘y’ ml of butan-1-ol is completely soluble in 100ml of water each, what is the relation between x and y?

(a) x > y

(b) x < y

(c) x = y

(d) x + y = 100

I got this question in homework.

This intriguing question comes from Amines Physical Properties topic in portion Amines of Chemistry – Class 12

Answer 1

Right option is (b) x < y

To elaborate: Alcohols are more polar than amines of comparable molecular masses and form stronger intermolecular hydrogen bonds with water. Therefore, the solubility of butan-1-ol is more than that of butan-1-amine.
