A. Physical state: the lower members are colourless liquids and have a characteristic smell and burning taste.
The higher members(with more than 12 carbons) are colourless wax like solids.
B. Solubility: The lower members are highly soluble in water.
Amongst isomeric alcohols, the solubility increases with branching.
C. Alcohols exists associated molecules due to intermolecular hydrogen bonds.
D. Boiling points: The lowers members have low boiling points.
With the increase in molecular weight, the boiling points keep on increasing gradually.
e. Density: Generally alcohols are lighter than water.
Density of alcohols increases with molecular mass.
F. Alcohols have intoxicating effects.
Methanol is poisonous.
Ethanol is used for drinking purposes.
