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) : 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 :
  1. (A)Both Statement I and Statement II are incorrect
  2. (B)Statement I is correct but Statement II is incorrect
  3. (C)Both Statement I and Statement II are correct
  4. (D)Statement I is incorrect but Statement II is correct✓ Correct

Answer: (D)

Solution

Statement I is incorrect — oxidation state is assigned by electronegativity of the bonded atoms, not by 'electron-gain-enthalpy' as phrased. Statement II is correct — pπ–pπ bonding is most prevalent in second-period elements. So I incorrect, II correct. Option (4).
