- CA, B and C Only
- DA, B, C and D
Correct answer
C. A, B and C Only
Step-by-step solution
Analyzing geometry and hybridization: A. IF₃: Iodine has 7 valence electrons, forms 3 bonds with F, leaving 2 lone pairs. Total electron pairs = 5 (trigonal bipyramidal geometry). Molecular shape is T-shaped. Hybridization = sp³d. CORRECT. B. IF₅: Iodine forms 5 bonds with F and has 1 lone pair. Total electron pairs = 6 (octahedral geometry). Molecular shape is square pyramidal with 1 lone pair in axial position. Hybridization = sp³d². CORRECT. C. IF₇: Iodine forms 7 bonds with F and has 0 lone pairs. Total electro
