Question

Among the following, the surfactant that will form micelles in aqueous solution at the lowest molar concentration at ambient condition is:-

पर्याय

• \[\ce{CH3(CH2)15N+(CH3)3Br–}\]

• \[\ce{CH3(CH2)11OSO^{-}3Na+}\]

• \[\ce{CH3(CH2)6CQO-Na+}\]

• \[\ce{CH3(CH2)11N+(CH3)3Br-}\]

Answer 1

\[\ce{CH3(CH2)15N+(CH3)3Br–}\]

Explanation:

The surfactant cetly trim ethyl ammonium bromide \[\ce{CH3(CH2)15N+(CH3)3Br–}\] with max^m molecular mass will form micelle at the lowest cmc.
