Which of the following alcohol is least soluble in water
Options
(a) CH₃OH
(b) C₄H₉OH
(c) C₃H₇OH
(d) C₁₀H₂₁OH
Correct Answer:
C₁₀H₂₁OH
Explanation:
The solubility of an alcohol decreases with the increase of its molecular mass (As the hydrophobicity of alkyl group increases). Molecular masses of CH₃OH, C₄H₉OH, C₃H₇OH and C₁₀H₂₁OH are 32,74,60 and 158 respectively. Therefore C₁₀H₂₁OH is the least soluble in water.
