NEETChemistryCarboxylic Acid Derivatives
Statement (A) Carboxylic acid can be obtained by the reaction of R- C N with H ₃ O under mild reaction conditions. Statement (B) Hydrolysis of R- C N in alkaline aqueous medium gives R- COON Na and NH ₃ as products. The correct answer is
Options
- ABoth (A) and (B) are correct
- BBoth (A) and (B) are not correct
- C(A) is correct, but (B) is not correct
- 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- CN . Therefore, statement (A) is incorrect. When alkyl cyanide hydrolysed in presence of alkaline medium, R- COOO ⁻+ a - Na and ammonia gas are obtained Therefore, statement (4) is correct.
