Question

For each reaction below identify the electrophile and the nucleophile

(a)

(b)

(c)

Step-by-Step Solution

Verified

Answer

(b)

Nucleophile Electrophile

1Nucleophile

A nucleophile is a substance that seeks a nucleus or positive charge, as benzene is negatively charged and electron-rich. Therefore, it is a nucleophile.

2Electrophile

The nitro group is positively charged and electron-deficient. It seeks electrons. Therefore, it acts as an electrophile as shown:
