Question
Evaluate the following statements related to group 14 elements for their correctness. (A) Covalent radius decreases down the group from C to Pb in a regular manner. (B) Electronegativity decreases from C to Pb down the group gradually. (C) Maximum covalence of C is 4 whereas other elements can expand their covalence due to presence of d orbitals. (D) Heavier elements do not form p-p bonds. (E) Carbon can exhibit negative oxidation states. Choose the correct answer from the options given below: (A) (C), (D) and (E) Only (B) (A) and (B) Only (C) (A), (B) and (C) Only (D) (C) and (D) Only
💡 Solution & Explanation
(A) Down the group; radius increases (B) EN does not decrease gradually from C to Pb. (C) Correct. (D) Correct. (E) Range of oxidation state of carbon ; –4 to +4
