Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Match the column
Column I (Molecules/ions) | Column II (Properties) |
|---|---|
(A) | (P) orbital is involved in hybridisation of central atom |
(B) | (Q) Maximum number of atoms in a plane = 5 |
(C) | (R) The axial (M-X) bond length is shorter than the equitorial (M-X) bond length |
(D) | (S) It has atleast one angle less than |
| (T) It has two lone pair on central atom |
Options:
Answer:
Solution:
ICl₄⁻
Square planar → 2 lone pairs → T
Maximum atoms in plane = 4 → here Q? (sometimes considered 5 including lone pairs)
dz² orbital involved → P
Has angles < 120° → S
OClF₃
Seesaw geometry → axial vs equatorial → dz² orbital participates → P
Some angles < 120° → S
POCl₃
Tetrahedral → bond angles slightly < 109.5° → S
IF₇
Pentagonal bipyramidal → dz² orbital → P
Axial bond shorter than equatorial → R
Some angles < 120° → S
