13.4 Arrange the following:
(vi) In increasing order of solubility in water:
More extensive is the hydrogen bonding, more is the solubility in water. contains two H atom while contains only one. So, the undergoes extensive hydrogen bonding. Hence its solubility is more than in water. On increasing the molecular mass of amines decreases its solubility in water because of an increase in bulky hydrophobic groups.
Thus the increasing order of solubility in water is-
