The Substance Most Likely to Form a Micelle Is

Question

The substance most likely to form a micelle is
A) acetic acid
B) sodium palmitate
C) methyl alcohol
D) acetone

Accepted Answer

Micelles are formed by amphipathic molecules, which have both hydrophilic and hydrophobic regions. Sodium palmitate is a fatty acid salt and it has both hydrophilic (ionic carboxylate group) and hydrophobic (long hydrocarbon chain) regions, making it likely to form micelles in water.
