Consider the given statements about critical micelle concentration in aqueous solutions and select the correct statement
Options
- AThe CMC increases as the length of the hydrophobic tail increases
- BIonic surfactants have higher CMC as compared to non-ionic surfactants containing equivalent hydrophobic groups
- CNon ionic surfactants have higher CMC as compared to ionic surfactants containing equivalent hydrophobic groups
- DSurfactants containing more than one hydrophilic group show smaller CMC than those with one hydrophilic group with the hydrophobic group being equivalent in both
Correct answer
B. Ionic surfactants have higher CMC as compared to non-ionic surfactants containing equivalent hydrophobic groups
Step-by-step solution
Ionic surfactants have much higher CMC than non ionic surfactants
