A metal, forms chlorides in its +2 and +4 oxidation states. Which of the following statements about these chlorides is incorrect?
Options:(select one or more)
Answer:
B, C, D
Solution:
Metal M forms MCl₂ (+2 state) and MCl₄ (+4 state). In heavier Group 14 elements, the +2 oxidation state is more stable due to inert pair effect.
MCl₂ is more ionic than MCl₄ → Correct, because M²⁺ has lower polarising power.
MCl₂ is more easily hydrolysed than MCl₄ → Incorrect, because MCl₄ is more covalent and hydrolyses more easily.
MCl₂ is more volatile than MCl₄ → Incorrect, because covalent MCl₄ is more volatile.
MCl₂ is more soluble in anhydrous ethanol than MCl₄ → Incorrect, because covalent MCl₄ dissolves more readily in organic solvents.
Correct Answer: (B), (C), (D)
