Alcohol Reactions | MCQs

Explanation

When an alcohol reacts with an alkyl magnesium halide (Grignard reagent), the product is an alkane.

The Grignard reagent acts as a strong base, removing the acidic hydrogen from the alcohol's hydroxyl group (-OH) and forming a new carbon-hydrogen (C-H) bond, thus creating an alkane.

The other product is a magnesium alkoxide salt. 

Explanation

• CH3-OH is the molecular formula for methanol, which is an alcohol.

Key Points:

• CH3-CHO is the molecular formula for acetaldehyde, which is an aldehyde.
• CH3-CH2-O-CH3 is the molecular formula for diethyl ether, which is an ether.
• HCOOH is the molecular formula for formic acid, which is a carboxylic acid.
