Question

Given below are two statements : Statement (I) : The oxidation state of an element in a particular compound is the charge acquired by its atom on the basis of electron gain enthalpy consideration from other atoms in the molecule. Statement (II) : pπ-pπ bond formation is more prevalent in second period elements over other periods. In the light of the above statements, choose the most appropriate answer from the options given below :

Accepted Answer

Statement I is incorrect but Statement II is correct. Statement I is incorrect because the oxidation state is defined based on the hypothetical charge an atom would have if all bonds were ionic, rather than solely on electron gain enthalpy. Statement II is correct as pπ-pπ bonding is indeed more favorable in second period elements due to their smaller size and greater ability to overlap p orbitals.
