Select the correct statement regarding the molecular geometries of ICl ₄^- , SF ₄ , and CH ₄ .

Step-by-step solution

For ICl ₄^- , the central iodine atom has 7 valence electrons. The negative charge adds 1 electron, giving 8 valence electrons. It forms 4 single bonds with chlorine atoms and has 2 lone pairs. The steric number is 4 + 2 = 6 , corresponding to sp^3d^2 hybridisation. The molecular geometry is square planar. For SF ₄ , the central sulfur atom has 6 valence electrons. It forms 4 single bonds with fluorine atoms and has 1 lone pair. The steric number is 4 + 1 = 5 , corresponding to sp^3d hybridisation. The molecular ge
