Which of the following is not a surfactant?

Answer»

`CH_(3)-(CH_(2))_(15)-N^(+)(CH_(3))_(3)Br^(-)`
`CH_(3)-(CH_(2))_(14)-CH_(2)NH_(2)`
`CH_(3)-(CH_(2))_(16)-CH_(2)OSO_(2)^(-)NA^(+)`
`OHC-(CH_(2))_(14)-CH_(2)-COO^(-)Na^(+)`

SOLUTION :`CH_(3)-(CH_(2))_(14)-CH_(2)-NH_(2)` is not a surfactant( or detegent ).
