Which of the following is a false statement?a)Free radicals, carbonium...
The false statement among the given options is option 'C', which states that the electronegative atom in the carbon chain produces the I effect. This statement is incorrect because the electronegative atom in a carbon chain actually produces the -I effect.

Let's break down each option and understand why the other statements are true.

a) Free radicals, carbonium ions, or carbanions are reaction intermediates:
- This statement is true. Free radicals, carbonium ions, and carbanions are all reactive intermediates that can form during organic reactions. They are highly reactive species and play a crucial role in many organic reactions.

b) Reaction between methane and chlorine in the presence of sunlight proceeds via free radical:
- This statement is true. When methane (CH4) reacts with chlorine (Cl2) in the presence of sunlight, the reaction proceeds via a free radical mechanism. The chlorine molecules are homolytically cleaved by the energy provided by sunlight, resulting in the formation of chlorine free radicals (Cl·). These chlorine free radicals then react with methane to form methyl free radicals (CH3·), which further react with chlorine molecules to generate more chlorine and methyl free radicals.

c) The electronegative atom in the carbon chain produces the I effect:
- This statement is false. The electronegative atom in a carbon chain actually produces the -I effect. The -I effect, or inductive effect, is the electron-withdrawing effect exerted by an electronegative atom in a molecule or functional group. It occurs due to the difference in electronegativity between the electronegative atom and carbon, causing the electron density to be pulled away from the carbon atom.

d) Homolytic fission of C-C bonds gives free radicals:
- This statement is true. Homolytic fission refers to the breaking of a covalent bond in a way that each atom retains one electron from the bond. When a C-C bond undergoes homolytic fission, two carbon atoms each retain one electron, resulting in the formation of two carbon-centered free radicals (·C-).

In conclusion, option 'C' is the false statement because the electronegative atom in a carbon chain produces the -I effect, not the I effect.
