Question

Assume that a single layer of phospholipids coat the water in a beaker. Which part of the phospholipid molecule will face the air?

Answer 1

The hydrocarbon tail will face the air as the Hydrocarbon tail of a Phospho lipid molecule is Hydrophobic

Answer 2

The head will face the water

The tail will face the air

Explanation:

The phospholipids are the molecules which are made up of the glycerol attached with a phosphate group (head) and a hydrocarbon (tail).

The hydrocarbon tail is a structure made of repeated Carbon and hydrogen and is non-polar which make them hydrophobic whereas the phosphate group is polar therefore the head structure is hydrophilic.

If the single layer of phospholipids in water is formed when the head portion due to its hydrophilic nature will form bonds with water whereas the tails with hydrophobicity will face the air.
