NEET 2017 · ChemistryPrevious Year Question

The correct statement regarding an electrophile is:

Answer: (D) An electrophile can be either a neutral or a positively charged species and can form a bond by accepting a pair of electrons from a nucleophile.. \textbf{Answer:} (d) \textbf{Solution:} An electrophile is an electron-deficient species that accepts a pair of electrons from a nucleophile to form a bond.

A.An electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from a nucleophile.
B.An electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from another electrophile.
C.Electrophiles are generally neutral species and can form a bond by accepting a pair of electrons from a nucleophile.
D.An electrophile can be either a neutral or a positively charged species and can form a bond by accepting a pair of electrons from a nucleophile.✓

Correct Answer

(D) An electrophile can be either a neutral or a positively charged species and can form a bond by accepting a pair of electrons from a nucleophile.

Solution & Explanation

\textbf{Answer:} (d) \textbf{Solution:} An electrophile is an electron-deficient species that accepts a pair of electrons from a nucleophile to form a bond. Electrophiles may be positively charged (e.g. $NO X_{2} X^{+}$ , $H X^{+}$ ) or neutral electron-deficient species (e.g. $BF X_{3}$ , $AlCl X_{3}$ , a carbonyl carbon). Hence the correct statement is (d).
