Which of the following statements about soaps and detergents is not true?
a. soaps form micelles in solution.
b. the hydrophilic end has the hydrocarbon chain.
c. the hydrophobic end has the hydrocarbon chain.
d. the hydrophilic end is ionic.

The answer is B. the hydrophilic end has the hydrocarbon chain.

Explanation:

That answer is wrong because soap and detergent form a bilayer with hydrophilic and hydrophobic ends.

the hydrophilic end interacts with polar compound such as water because that end is ionic and charged, it is composed of carbon and Oxygen and forms dipole interaction and electrostatic interactions.

the hydrophobic end is the non polar end, it is composed of carbon and hydrogen chain (Hydrocarbon) which are non-polar due to equal electronegativity between carbon and hydrogen.

that is why answer B is not true, the hydrophilic end does not have the hydrocarbon chain, the hydrocarbon chain is on the hydrophobic end.
