Which of the following can form iconic micelles in water?
Which of the following can form iconic micelles in water?
starch molecules
sodium lauryl sulphate
iodine molecules
S8 molecules
The Correct Option is B
Solution and Explanation
Step 1: Understand the Concept of Ionic Micelles:
Ionic micelles are formed by surfactant molecules in water. These surfactants have both hydrophilic (water-loving) and hydrophobic (water-hating) parts. The hydrophobic part forms the core of the micelle, and the hydrophilic part faces outward in contact with water. Ionic surfactants can easily form ionic micelles in water because their ionic head groups help to stabilize the structure in the aqueous environment.
Step 2: Analyze the Options:
We need to identify which of the following can form ionic micelles in water:
Option 1: Starch molecules
Starch molecules are complex carbohydrates that do not have the necessary ionic nature to form ionic micelles. They do not form micelles in water. Hence, this option is incorrect.
Option 2: Sodium lauryl sulphate (SLS)
Sodium lauryl sulphate is an anionic surfactant with a negatively charged sulfate group. This allows it to form ionic micelles in water. Hence, this option is correct.
Option 3: Iodine molecules
Iodine is a nonpolar molecule and does not have the ability to form ionic micelles in water. Hence, this option is incorrect.
Option 4: S8 molecules
S8 molecules are nonpolar molecules and cannot form ionic micelles in water. Hence, this option is incorrect.
Final Answer:
The correct answer is Sodium lauryl sulphate, as it can form ionic micelles in water.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
