Explain why methyl alcohol is soluble in water in all proportions, while stearyl alcohol [CH3(CH2)16OH] is a waxy solid that is not soluble in water.

Interpretation Introduction

Interpretation: Methyl alcohol is soluble in water while stearyl alcohol is insoluble in water is to be explained.

Concept introduction: An alcohol is defined as an organic compound which consists of a hydroxyl functional group (-OH) bonded to a saturated carbon atom. The solubility of alcohols is due to the presence of hydroxyl group which is able to form hydrogen bonds with water molecules. Their solubility decreases with increasing the non polar hydrocarbon chain within the molecule.

To determine: The explanation of methyl alcohol is soluble in water while stearyl alcohol is not.



An alcohol consists of two parts, the polar OH group and the non polar hydrocarbon chain which is shown below,

Figure 1

Methyl alcohol has one carbon chain and a OH group. As water is polar in nature it attracts OH group. On the other hand the non polar carbon chain is repelled. Therefore, the solubility of alcohols is determined by the stronger of the two forces
