Which one of the following is not a surfactant?

Options

A. `CH_(3)(CH_(2))_(15)-overset(+)(N)(CH_(3))_(3)Br^(-)`
B. `CH_(3)(CH_(2))_(14)CH_(2)NH_(2)`
C. `CH_(3)(CH_(2))_(16)CH_(2)OSO_(2)^(-)Na^(+)`
D. `OHC(CH_(2))_(14)CH_(2)COO^(-)Na^(+)`

Answer

B

Explanation

Surfactants are those substances which are prefentially adsorbed at the interfaces like air-water, oil-water etc. To behave as a surfactant, the molecule or ion must have both a hydrophobic end end a hydrophilic end.
Thus compound in option `(2)` is not a surfactant.
