Question

Which of the following is not a correct match? (1) Methane nitrile $ C{{H}_{3}}CN $ (2) Iso butyric acid $ {{(C{{H}_{3}})}_{3}}C-COOH $ (3) Crotonic acid $ C{{H}_{3}}-CH=CH-COOH $ (4) Acetonitrile $ C{{H}_{3}}-C\equiv N $

• A. $ 1,4 $
• B. $ 2,3 $
• C. $ 1,3 $
• D. $ 2,4 $

Answer 1

Answer: (A)

Methane nitrile and acetonitrile is not matching. $ \left. \begin{align} & C{{H}_{3}}-C\equiv N \\ & and \\ & C{{H}_{3}}CN \\ \end{align} \right\}these\,are\,ethane\,nitrile $
