Question

The hydrophobic end of lauryl sulphate is​

Answer 1

Answer:

A molecule with head and tail.

Explanation:

Sodium lauryl sulfate is a surfactant, which means a molecule that has ampiphilic properties. This means the sulfate head group (shown by the pink shading in the diagram below) is hydrophilic and water soluble, while the 12-carbon-long chain is hydrophobic and water insoluble.

Answer 2

Hydrophobic end of lauryl sulphate is - C12H25.

Lauryl sulphate is an amphipathic molecule indicating presence of both hydrophobic and hydrophilic chains. Hydrophilic head is the part containing OSO3-. Hydrophobic tail is the alkyl chain containing twelve carbon atoms and 25 hydrogen atoms.

The lauryl sulphate finds its use as detergents for cleaning purposes and degreasers. Sulfonic acid and dodecanol undergo esterification to produce resultant compound.
