OH and solubility
(1/1)
Jill:
Is it true? the more OH groups an alcohol has the more soluble it is in water?
Edited title for clarity. Mitch
Mitch:
in general, yes.
AWK:
Cellulose or starch have thousends hydroxyl grups and are insoluble in water.
Solubility also depends on mass of molecule.
Donaldson Tan:
Solubility would depends on:
1. length of the carbon chain
- big molecules are insoluble virtue of their size
2. No. of -OH available
- more OH present = more H-bonding sites
3. hydroxyl group arrangement
- -OH are projected towards each other in cellulose
- whether the OH is available for H-bonding
