Q62 / 180 · NEET 2026 (Re-NEET) · Chemistry
One of the products formed in the following reaction is
- Correct answerA
- B
- C
- D
Solution
Cyclohexylmagnesium bromide is a Grignard reagent, which acts as a strong base.
Cyclohexylamine contains active (acidic) hydrogen atoms attached to the nitrogen atom.
When a Grignard reagent reacts with a compound containing an active hydrogen, an acid-base reaction occurs preferentially. The Grignard reagent abstracts a proton to form the corresponding alkane.
$C_6H_{11}MgBr + C_6H_{11}NH_2 \rightarrow C_6H_{12} + C_6H_{11}NHMgBr$
Thus, cyclohexane ($C_6H_{12}$) is formed as one of the products.
