Given below are two statements: One is labelled as Assertion A and...

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R:

Assertion A: Alcohols react both as nucleophiles and electrophiles.

Reason R: Alcohols react with active metals such as sodium, potassium and aluminum to yield corresponding alkoxides and liberate hydrogen.

In the light of the above statements, choose the correct answer from the options given below:

Options

  1. AA is false but R is true.
  2. BA is true but R is false.
  3. CBoth A and R are true and R is the correct explanation of A
  4. DBoth A and R are true but R is NOT the correct explanation of A

Correct answer

D. Both A and R are true but R is NOT the correct explanation of A

Step-by-step solution

Alcohols as nucleophile:The bond between O−HO - H is broken when an alcohol reacts as a nucleophile. Alcohols as electrophiles:The bond between C−OC - O is broken when alcohols react as electrophiles.

Alcohols react with active metals such as sodium, potassium and aluminium to yield corresponding alkoxides and hydrogen.

2R−OH+2Na→2RONa+H22R - OH +2 Na \to 2 RONa + {H}_{2}

Assertion (A) and Reason (R) is correct but Reason (R) is not the correct explanation.
