Variation in alcohol solubility

Videonummer 11939752
Variation in alcohol solubility. Animation showing molecular models of three alcohols of increasing molecular weight and their relative solubility in water. Alcohols are hydrocarbons with a hydroxyl (OH) group attached. Here, the atoms are colour-coded spheres: carbon (grey), hydrogen (white) and oxygen (red). These are primary alcohols, with the OH group on the end of a straight-chain unbranched alkane chain. The first alcohol to be highlighted (green flash) is ethanol (C2.H5.OH) which is miscible in water. The second alcohol to be highlighted is butanol (C4.H9.OH) with a solubility of 73 grams per litre of water. The third alcohol to be highlighted is hexanol (C6.H13.OH) with a solubility of 5.9 grams per litre of water. The trend for the primary alcohols is for solubility in water to decrease as size and molecular weight increases.
