Question

The soap molecule has a

• A. Hydrophilic head and a hydrophobic tail
• B. Hydrophobic head and a Hydrophilic tail
• C. Hydrophobic head and a hydrophobic tail
• D. Hydrophilic head and a hydrophilictail

Answer 1

The correct option is A Hydrophilic head and a hydrophobic tail

A hydrophilic molecule is one that is typically charge-polarized and capable of hydrogen bonding, enabling it to dissolve more readily in water than in oil. Hydrophilic and hydrophobic molecules are also known as polar molecules and nonpolar molecules, respectively. Some hydrophilic substances do not dissolve. This type of mixture is called a colloid.
Soap, which is amphipathic (possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving) properties) , has a hydrophilic head and a hydrophobic tail, allowing it to dissolve in both water and oil.
Option "A" is correct.
