14.1 properties of alcohols Flashcards
1
Q
what is the alcohols functional group?
A
-OH
2
Q
why do alcohols have a higher boiling point than alkanes?
A
- alcohols can form hydrogen bonds
- more energy needed to overcome hydrogen bonds
3
Q
what are compounds with low boiling points said to have?
A
high(er) volatility

Q
state and explain the trend in the boiling point of the alcohols as the length of the carbon chain increases
A
- as the chain length increases the boiling point increases due to stronger London forces (induced dipole- dipole interactions)
- due to more electrons present
- more energy is required to break these stronger London forces
