Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Number of sets in which specie has more covalent character than .
(BeCl₂, BeI₂) ; (AlCl₃, MgCl₂) ; (LiF, KF) ; (ZnCl₂, HgCl₂) ; (MgO, MgF₂) ; (SnCl₂, SnCl₄)
Answer:
Solution:
The covalent character is favored by smaller cation size, larger anion size, higher cation charge, and pseudo-noble gas configuration.
1. (BeCl₂, BeI₂): BeI₂ has more covalent character due to larger I⁻ anion.
2. (AlCl₃, MgCl₂): AlCl₃ has more covalent character due to higher charge and smaller size of Al³⁺.
3. (LiF, KF): LiF has more covalent character due to smaller Li⁺ cation.
4. (ZnCl₂, HgCl₂): HgCl₂ has more covalent character due to larger size and pseudo-noble gas configuration of Hg²⁺.
5. (MgO, MgF₂): MgO has more covalent character due to larger O²⁻ anion.
6. (SnCl₂, SnCl₄): SnCl₄ has more covalent character due to higher charge of Sn⁴⁺.
Sets where the 1st specie has more covalent character: (AlCl₃, MgCl₂), (LiF, KF), (SnCl₂, SnCl₄).
Total = 3 sets.
