Alcohols Flashcards
1
Q
What are some physical properties of alcohols? (3)
A
- Less volatile
- Higher melting points
- Differences get smaller as carbon chain length increases
2
Q
Why do alcohols have higher melting points than alkanes? (5)
A
- Alkanes are non-polar
- Only held together by weak intermolecular forces (London forces)
- OH group in alcohols is polar
- Therefore molecule is polar
- Can form weak intermolecular forces (London forces) AND strong hydrogen bonds between OH groups
