Question

In which of the following pairs both are nucleophiles?a) BF₃, AlCl₃ b) NO⁺₂, Cl⁻c) CN⁻, NH₃ d) Br⁺, BCl₃

Answer 1

answer must be (c)
as only that pair has valenxe electrons ;ability to give.

hope my answer helps you.

Answer 2

Answer: Option (c) is the correct answer.

Explanation:

A nucleophile is defined as a specie with is electron rich in nature and has the ability to donate an electron to an electron deficient specie.

A nucleophile usually contains a negative charge or a lone pair.

For example, ammonia ($NH_{3}$) molecule contains a lone pair of electron.

Hence, it acts as a nucleophile.

Also, in $CN^{-}$ due to the presence of a negative charge there it is also a nucleophile.

Thus, we can conclude that a pair which contains $CN^{-}$ and $NH_{3}$ are both nucleophiles.
