Label the hydrophilic and hydrophobic parts in the following compounds : (i) CH_(3)(CH_(2))_(10)CH_(2)OSO_(3)^(-)Na^(+) (ii) CH_(3)(CH_(2))_(15)-overset(+)N(CH_(3))_(3)Br^(-) (iii) CH_(3)(CH_(2))_(16)COO(CH_(2)CH_(2)O)_(n)CH_(2)CH_(2)OH

Answer»

Solution :(i) `underset("HYDROPHOBIC part")ubrace(CH_(3)(CH_(2))_(10))-underset("Hydrophilic part")ubrace(OSO_(3)^(-)Na^(+))`
(II) `underset("Hydrophobic part")ubrace(CH_(3)(CH_(2))_(15))-underset("Hydrophilic part")ubrace(overset(+)N(CH_(3))Br^(-))`
(III) `underset("Hydrophobic part")(ubrace(CH_(3)(CH_(2))_(6)))-underset("Hydrophilic part")ubrace(COO(CH_(2)CH_(2)O)_(n)CH_(2)CH_(2)OH)`
