The solubility of alcohol decrease with increasing numbers of carbon atom explain​
Oxana [17]

As the length of the carbon chain increases, the polar OH group becomes an ever smaller part of the molecule, and the molecule becomes more like a hydrocarbon. The solubility of the alcohol decreases correspondingly.
