Worked Solution & Example Answer:The structure of a soapless detergent molecule is given below - Scottish Highers Chemistry - Question 12 - 2022
Step 1
Which line in the table describes a step in the cleansing action of a soapless detergent?
Answer
To determine the correct answer, we examine the actions of the head and tail sections of the soapless detergent. The head, which is hydrophilic, interacts with water, while the tail, being hydrophobic, interacts with oils. According to the roles of these sections, the correct description is that:
- The hydrophilic head dissolves in water, and the hydrophobic tail dissolves in oil.
Thus, the correct choice is B: 'The hydrophilic head dissolves in water. The hydrophobic tail dissolves in oil.'
