Solubility - physical characteristics of carbonyl compounds

Aldehydes and ketones upto 4 carbon atoms are miscible along with water. This is because of the existence of hydrogen bonding among the polar carbonyl group and water molecules as illustrated below:  

As the increase in the size of alkyl group, solubility decreases and the compounds with much more than four carbon atom are practically insoluble in water. Though, each and every aldehydes and ketones are soluble in organic solvents like ether, alcohol, etc. The ketones are good solvents themselves.
