Wrong Statement: The addition of chlorine to methane in the presence of sunlight is called addition reaction.

Explanation:
In organic chemistry, addition reactions occur when two or more reactants combine to form a single product. The addition of chlorine to methane in the presence of sunlight is not an addition reaction but rather a substitution reaction.

Substitution reaction:
In a substitution reaction, one atom or group of atoms is replaced by another atom or group of atoms. In the case of the addition of chlorine to methane, one hydrogen atom from methane is replaced by a chlorine atom.

Addition reaction:
In an addition reaction, two or more reactant molecules combine to form a single product molecule. This reaction involves the breaking of a double or triple bond and the addition of new atoms or groups to the reactant molecule. An example of an addition reaction is the hydrogenation of vegetable oils.

Correct examples of addition reactions:
1. Hydrogenation of vegetable oils: Vegetable oils, which are unsaturated compounds, can be hydrogenated to form saturated compounds. This reaction involves the addition of hydrogen gas (H2) in the presence of a catalyst such as nickel (Ni).
2. Addition of water to ethene: Ethene (C2H4) can undergo an addition reaction with water (H2O) to form ethanol (C2H5OH). This reaction is commonly known as hydration.

In conclusion, the addition of chlorine to methane in the presence of sunlight is not an addition reaction but a substitution reaction. The correct statement is option 'B'.

Detergents are also called surface-active agents (surfactants). These have two distinct parts: one hydrophilic spherical part and another hydrophobic long tail made of carbons chain. Two experiments ‘A’ and ‘B’ were carried out. In experiment ‘A’, surfactant was added in a beaker containing water. In experiment ‘B’, surfactant was added in a beaker containing hexane.Following are possible results in these experiments:I. In experiment ‘A’ (see figure ‘a’) micelle is formed, where the hydrophobic part is inside the micelle and the hydrophilic part is outside the micelle.II. In experiment ‘B’ (see figure ‘b’) micelle of reverse type is formed where the hydrophilic part is inside the micelle and the hydrophobic part is outside the micelle.III. Micelle of reverse type is formed in experiment ‘A’.IV. Micelles are large enough to scatter light in ‘A’.
