The solubility of Alcohols is comparatively more in water than that of the solubility of hydrocarbons of comparable molecular masses. Justify the above fact.
Due to the presence of – OH group, alcohols form H – bonds with water. As a result, alcohols are comparatively more soluble in water than hydrocarbons of comparable molecular masses.

Why does nitrogen show catenation properties less than phosphorus?
Catenation is much more common in phosphorous compounds than in nitrogen compounds. This is because of the relative weakness of the N−N single bond as compared to the P−P single bond. Since nitrogen atom is smaller, there is greater repulsion of electron density of two nitrogen atoms, thereby weakening the N−N single bond
