Question

Explain why ethanol has a higher boiling point than ethane

Answer 1

HELLO MACHII ✋...


✨Alcohols have higher boiling points than their corresponding alkane (eg ethanol has a higher boiling point than ethane) because the –OH group has the effect of strengthening the intermolecular forces.

✨Longer chain alcohols are less soluble because they behave more like an alkane and tend to float on top of the water.


Hope it help you!! ☺️ ☺️

Answer 2

Answer:

Ethanol has a higher boiling point than ethane

Explanation:

Ethanol has:

• LDF (London dispersion force) because all compounds have this force

• Hydrogen bond because of -OH (hydrogen bond form when H is bonded with N, O, or F)  

Ethane is non polar, because it equally shares electrons so it just has a LDF

Strength of each intermolecular force:

• Ionic > hydrogen bonding > dipole dipole > LDF

Because ethanol has a stronger intermolecular force, ethanol will have a higher boiling point than ethane
