Suggest the reason why phospholipid
molecules are arranged in a bilayer form
with fatty acid tails facing inward

Interactions with water cause the phospholipids to form a bilayer, with hydrophobic fatty acid tails inside the bilayer and hydrophilic groups exposed to water. This basic structure makes the membrane a barrier to hydrophilic molecules. The interior of the membrane is fluid, with a viscosity about equal to olive oil. Since the tails are hydrophobic, they face the inside, away from the water and meet in the inner region of the membrane. Since the heads are hydrophilic, they face outward and are attracted to the intracellular and extracellular fluid.

Explanation:

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.
