Statement (A) Carboxylic acid can be obtained by the reaction of R−C≡NR-\mathrm{C} \equiv \mathrm{N} with H3O⊕\mathrm{H}_3 \stackrel{\oplus}{\mathrm{O}} under mild reaction conditions. Statement (B) Hydrolysis of R−C≡NR-\mathrm{C} \equiv \mathrm{N} in alkaline aqueous medium gives R−COONNaR-\mathrm{COON} \mathrm{Na} and NH3\mathrm{NH}_3 as products. The correct answer isStatement (A) Carboxylic acid can be obtained by the reaction of R-C N with H_3 O under mild reaction conditions.Statement (A) Carboxylic acid can be obtained by the reaction of R-C N with H_3 O under mild reaction conditions.

Options

  1. ABoth (A) and (B) are correct
  2. BBoth (A) and (B) are not correct
  3. C(A) is correct, but (B) is not correct
  4. D(A) is not correct but (B) is correct

Correct answer

D. (A) is not correct but (B) is correct

Step-by-step solution

Carboxylic acid can be obtained by complete hydrolysis of R−CNR-\mathrm{CN}. Therefore, statement (A)(A) is incorrect. Statement (A) Carboxylic acid can be obtained by the reaction of R-C N with H_3 O under mild reaction conditions.
When alkyl cyanide hydrolysed in presence of alkaline medium, R−COOO−+a−NaR-\mathrm{COOO}^{-}+\mathrm{a}-\mathrm{Na} and ammonia gas are obtainedStatement (A) Carboxylic acid can be obtained by the reaction of R-C N with H_3 O under mild reaction conditions.
Therefore, statement (4) is correct.
