 Methanol has the shortest carbon chain of all alcohols (one carbon atom) followed by ethanol (two carbon atoms), and 1-propanol along with its isomer 2-propanol, all being miscible with water.Tert-Butyl alcohol, with four carbon atoms, is the only one among its isomers to be miscible with water.Cyclodextrins are used to make pharmaceutical solutions by capturing hydrophobic molecules as guest hosts.
