In a reaction

In a reaction reagents ‘ X ’ and ‘ Y ’ respectively are:

reagents ‘XX’ and ‘YY’ respectively are:

Options

  1. A(CH3CO)2O/H+{\left({CH}_{3}CO\right)}_{2}O / {H}^{+} and CH3OH/H+,∆{CH}_{3}OH / {H}^{+}, ∆
  2. B

    (CH3CO)2O/H+{\left({CH}_{3}CO\right)}_{2}O / {H}^{+} and (CH3CO)2O/H+{\left({CH}_{3}CO\right)}_{2}O / {H}^{+}

  3. CCH3OH/H+,∆{CH}_{3}OH / {H}^{+}, ∆ and CH3OH/H+,∆{CH}_{3}OH / {H}^{+}, ∆
  4. DCH3OH/H+∆{CH}_{3}OH / {H}^{+} ∆ and (CH3CO)2O/H+{\left({CH}_{3}CO\right)}_{2}O / {H}^{+}

Correct answer

A. (CH3CO)2O/H+{\left({CH}_{3}CO\right)}_{2}O / {H}^{+} and CH3OH/H+,∆{CH}_{3}OH / {H}^{+}, ∆

Step-by-step solution

When salicylic acid is heated with methyl alcohol, the carboxyl group of salicylic acid is esterified producing a strong-smelling liquid ester (methyl salicylate). Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride.

In a reaction reagents ‘ X ’ and ‘ Y ’ respectively are: Hence, reagent ′Y′' Y ' and ′X′' X ' respectively are: CH3OH/H+,∆{CH}_{3}OH / {H}^{+}, ∆ and (CH3CO)2O/H+{\left({CH}_{3}CO\right)}_{2}O / {H}^{+}.
