Vedclass · Answer

(A) The Critical Micelle Concentration $(CMC)$ decreases as the length of the hydrophobic hydrocarbon chain increases. Longer hydrocarbon chains increase the hydrophobic effect,making micelle formation more favorable at lower concentrations. Comparing the chain lengths: Option $A$ has a $16$-carbon chain $(C_{16})$. Option $B$ has a $12$-carbon chain $(C_{12})$. Option $C$ has a $7$-carbon chain $(C_7)$. Option $D$ has a $12$-carbon chain $(C_{12})$. Since option $A$ has the longest hydrocarbon chain,it will form micelles at the lowest concentration.

Under identical conditions,which of the following surfactants will form micelles at its lowest concentration?
