Which of the following is a cationic detergent?a)Cetyltrimethyl ammoni...
Explanation:
Cationic Detergent:
- Cationic detergents are surfactants that contain positively charged hydrophilic (water-attracting) groups.
- These detergents are often used in fabric softeners and hair conditioners.
Option A: Cetyltrimethyl Ammonium Bromide
- Cetyltrimethyl ammonium bromide is a cationic detergent commonly used in laboratory settings.
- It has a positively charged quaternary ammonium group that enables it to interact with negatively charged surfaces.
- This detergent is effective in solubilizing lipids and proteins due to its cationic nature.
Option B: Sodium Dodecylbenzene Sulphonate
- Sodium dodecylbenzene sulphonate is an anionic detergent, not a cationic detergent.
- Anionic detergents have negatively charged hydrophilic groups.
Option C: Sodium Lauryl Sulphate
- Sodium lauryl sulfate is also an anionic detergent commonly found in personal care products.
- It is known for its foaming properties but is not cationic.
Option D: Sodium Stearate
- Sodium stearate is a soap and falls under the category of anionic detergents.
- It is often used in the manufacturing of solid soap bars.
Therefore, the correct answer is option A, cetyltrimethyl ammonium bromide, which is a cationic detergent due to its positively charged nature.
