Which of the following is a false statement?
Which of the following is a false statement?
Show Hint
Hydrogen bonding significantly raises boiling points. Alcohols boil higher than ethers of similar mass.
Updated On: Apr 15, 2025
- Methoxymethane has higher boiling point than ethanol.
- Alcohols are more soluble in water than hydrocarbons of comparable molecular mass.
- ortho- and para-nitrophenols are more acidic than phenols.
- Phenol is more acidic than alcohol.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Analyze boiling point factors.
Boiling point depends on intermolecular forces like hydrogen bonding, van der Waals forces, etc. Step 2: Compare methoxymethane and ethanol.
Methoxymethane (CH$_3$–O–CH$_3$) is an ether and shows dipole-dipole interactions but no hydrogen bonding.
Ethanol (CH$_3$CH$_2$OH) has strong hydrogen bonding due to the –OH group. Step 3: Result.
Hydrogen bonding increases boiling point. Hence, ethanol has a higher boiling point than methoxymethane. So, statement A is false.
