Write about the solubility of carboxylic acid compounds.

(N/A) $(i)$ Simple aliphatic carboxylic acids having up to four carbon atoms ($HCOOH, CH_3COOH, CH_3CH_2COOH$ and $CH_3CH_2CH_2COOH$) are miscible in water due to the formation of hydrogen bonds with water.
$(ii)$ The solubility decreases with an increasing number of carbon atoms.
$(iii)$ Higher carboxylic acids are practically insoluble in water due to the increased hydrophobic interaction of the hydrocarbon part.
$(iv)$ Benzoic acid,the simplest aromatic carboxylic acid,is nearly insoluble in cold water.
$(v)$ Carboxylic acids are also soluble in less polar organic solvents like benzene,ether,alcohol,chloroform,etc.
