Given below are four statements regarding the properties and trends of halogens and their oxides: (A) Chemical reactivity of an element can be determined by its reaction with oxygen and halogens. (B) The stability of oxides of halogens follows the decreasing order Cl > Br > I . (C) Chlorine oxides are highly reactive oxidizing agents and tend to explode. (D) Lower oxides of halogens are generally more stable than the

Options

  1. A(A), (B) and (C) only
  2. B(A) and (C) only
  3. C(A), (C) and (D) only
  4. D(B) and (C) only

Correct answer

B. (A) and (C) only

Step-by-step solution

Statement (A) is correct. Oxygen and halogens are highly electronegative and reactive, hence their reactions are used as benchmarks to determine the chemical reactivity of elements. Statement (B) is incorrect. The stability of halogen oxides follows the order I > Cl > Br . Iodine oxides are the most stable due to the greater polarizability of the iodine atom, while chlorine oxides are stabilized by multiple bond formation. Bromine oxides lack both characteristics and are the least stable. Statement (C) is correct.
