Question

Which of the following is/are nucleophiles?

• A. $C{H}_2=C{H}_2$
• B. $C{H}_{3}OH$
• C. $C{N}^{-}$
• D. All of the above.

Answer 1

The correct option is D All of the above.

A reagent which donates an electron pair to an electron deficient centre is known as nucleophiles.
(a) $C{H}_2=C{H}_2$ is a nucleophile since it has pi $e^{-}$s to donate.

(b) $C{H}_{3}OH$ is a nucleophile since it has lone pair $e^{-}$s on $\stackrel{..}{O}$ to donate.

(c) $C{N}^{-}$ has negatively charged species thus it also act as nucleophile.
Hence option (d) is correct
