Question

Which statement is not correct about alcohol? (A) Alcohol of less no. of carbon atoms is less soluble in water than alcohol of high no. of carbon atoms. (B) Alcohol is lighter than water. (C) Alcohol evaporates quickly. (D) All of these.

Tardigrade Admin · Accepted Answer

As the molecular weights of alcohols increases, the solubility in water decreases due to increase in hydrophobic group on the alcohol molecules.

C H_{3} - O H, C H_{3} - C H_{2} - O H, C H_{3} - C H_{2} - C H_{2} - O H Increasing hydrophobicity
