Grignard reagent is reactive due to___________________?
Correct answer: C. the polarity of C-Mg bond
- A. the presence of halogen atom
- B. the presence of magnesium atom
- C. the polarity of C-Mg bond
- D. all
Explanation
A Grignard reagent is reactive because the C-Mg bond is strongly polar, giving the carbon atom partial negative character and making it a powerful nucleophile. Students often choose magnesium because it is the distinctive metal in the reagent, but the bond polarity is what directly explains the carbon's reactivity.

About Nucleophilic Addition Reactions
Nucleophilic addition occurs at the polar carbonyl group of aldehydes and ketones, where a nucleophile attacks the electron-deficient carbon atom. Reactions with hydrogen cyanide, sodium bisulfite, alcohols and Grignard reagents are explained through tetrahedral intermediates, acid or base catalysis, and the different reactivity of aldehydes and ketones.
