Which of the following is not soluble in water?
Correct answer is : (D.) CH3CH2CH2CH2CH3
Explanation
Water is a polar solvent and only the substances having same intermolecular forces as water are soluble in water.
The major intermolecular forces present in water are hydrogen bonding and dipole-dipole intermolecular forces.
pentane CH3CH2CH2CH2CH3 neither has hydrogen bonding nor dipole-dipole intermolecular forces. Hence, pentane will not dissolve in water.
