- Alkanes
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
An alkyl magnesium halide (Grignard reagent) has a strongly basic carbon bonded to magnesium.
Step 2: Reaction with Water
Water acts as a proton donor.
\(\text{R-Mg-X}+\text{H}_{2}\text{O}\rightarrow\text{R-H}+\text{Mg(OH)X}\)
Step 3: Compare the options
The organic product R-H is an alkane, which is option (D).
Final Answer:
The Grignard reagent gives an alkane with water. \[ \boxed{\text{(D) }\text{Alkanes}} \]
