Micelles are formed from concentrated soap solutions above critical micelle concentration. Micelles are regarded as associate colloids as soap ions associate to give micelles. Which of the following give a positive micelle ?

Answer»

`CH_3-CH(CH_3)_2 -(CH_2)_(5)-N(CH_3)_2//HCl`
`C_17 H_35 COOH//KOH`
`C_12H_25SO_3H//KOH`
`C_17H_35COONa`

SOLUTION :`CH_3-underset(CH_3)underset(|)overset(CH_3)overset(|)(C)-(CH_2)_(5) - underset(CH_3)underset(|)overset(CH_3)overset(|)(NH^+)-CL^(-)`
