When a mixture of 1-hexanol and hexanoic acid in diethyl ether is shaken with an aqueous NaHCO3 solution, then which of the following is right distribution?
In ether | In sodium bicarbonate solution |
Sodium hexanoate | 1- hexanol |
1- hexanol | Hexanoic acid |
1- hexanol | Sodium hexanoate |

The correct order of increasing acidic strength is
phenol < ethanol < chloroacetic acid < acetic acid
ethanol < phenol < chloroacetic acid < acetic acid
ethanol < phenol < acetic acid < chloroacetic acid
chloroacetic acid < acetic acid < phenol < ethanol
