Among the following , the surfactant that will form nicelles in aqueous solution at the lowest nola concentration at amibemt conditions, is :
A
` CH_3 (CH_2)_(15)N^+ (CH_3)_3 Br^-`
B
`CH_3 (CH_2)_(11)OSO_3^(-) Na^+`
C
`CH_3 (CH_2)_(6)OSO_3^(-) Na^+`
D
` CH_3 (CH_2)_(11)N^+ (CH_3)_3 Br^-`
Text Solution
Verified by Experts
The correct Answer is:
a
Larger si the hydrophobic part in surfactant more is its ability to formn micelles at lower concentration and `CH_3(CH_2)_(15) N^+(CH_3)_3 Br^-` has longest hydrocarbon chain (i.e., hydrogphobic).
