Options

  1. AWhat distinguishes the surface of a solid in terms of molecular behavior?
  2. BWhat distinguishes the surface of a solid in terms of molecular behavior?
  3. CWhat distinguishes the surface of a solid in terms of molecular behavior?
  4. DWhat distinguishes the surface of a solid in terms of molecular behavior?

Correct answer

C. What distinguishes the surface of a solid in terms of molecular behavior?

Step-by-step solution

The major product obtained in the following reaction is:
LiAlH 4_{4} is a nucleophilic reducing agent, hence it will reduce −COOH-\mathrm{COOH} to CH2OH,−CO\mathrm{CH}_{2} \mathrm{OH},-\mathrm{CO} to −CHOH-\mathrm{CHOH} and −NO2-\mathrm{NO}_{2} to NH2\mathrm{NH}_{2} but does not reduce C=C\mathrm{C}=\mathrm{C} linkage.
