diethyl ether
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Acetic acid (CH3COOH) has the highest boiling point among the given options due to its strong capacity for hydrogen bonding.
Acetic acid (CH3COOH) has the highest boiling point among the given options due to the presence of strong intermolecular forces called hydrogen bonding.
The carboxyl group (-COOH) in acetic acid allows for hydrogen bonding with other acetic acid molecules,
This results in a significantly higher boiling point compared to the other compounds.
