Q 8.

Correct3

Incorrect-1

Chemical reaction of alcohols are mainly based on -{tex}\mathrm{OH}{/tex} group of alcohol. The oxygen atom of -{tex}\mathrm{OH}{/tex} group polarize both the {tex} \mathrm { C } - 0 {/tex} bond and the {tex} 0 - \mathrm { H } {/tex} bond of any alcohol. Polarization of the {tex} 0 - \mathrm { H } {/tex} bond makes the hydrogen partially positive and explain why alcohols are weak acids. Polarization of the {tex} \mathrm { C } - 0 {/tex} bond makes the carbon atoms partially positive. The polarization of {tex} \mathrm { C } - 0 {/tex} bond is responsible for the weak basic character of alcohols. On the basis of the above explanation, alcohols give two types of reactions.Which of the following alcohols is the strongest acid?

{tex} \mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { OH } {/tex}

{tex} \left( \mathrm { CH } _ { 3 } \right) _ { 3 } \mathrm { COH } {/tex}

{tex} \mathrm { CH } _ { 3 } \mathrm { OH } {/tex}

{tex} \left( \mathrm { CH } _ { 3 } \right) _ { 2 } \mathrm { CHCH } _ { 2 } \mathrm { OH } {/tex}
