2. CH₃CH₂OH
3 the -CH₂(CH₂) ₁₁CH₃ group
4. the -NH₃⁺ group

Question

Quizplus · Accepted Answer

The -CH2SO3- group is hydrophilic due to the presence of the sulfonate group. CH3CH2OH is hydrophilic because it contains an alcohol group. The -CH2(CH2)11CH3 group is hydrophobic due to its long hydrocarbon chain. The -NH3+ group is hydrophilic because it is a charged ammonium ion.
