Question

A standard commercial synthetic surfactant is discovered to easily form rigid micelles in a pure aqueous medium. If the total length of its massive hydrophobic hydrocarbon tail is significantly increased via synthesis, what strictly occurs to the numerical value of its Critical Micelle Concentration (CMC)?

Prashant Kotian · Accepted Answer

Correct answer: A. The Critical Micelle Concentration (CMC) relies entirely on the delicate thermodynamic balance of the surfactant. Increasing the bulk length of the non-polar hydrophobic tail massively increases the molecule's intense natural repulsion for water, thereby driving the monomers to aggressively aggregate into micelles much easier, strictly at a vastly lower threshold concentration.
