Question

Consider the following orbitals : (i) 3px (ii) 4dz^2 (iii) 3dx^2-y^2 (iv) 3dyz. Then calculate value of 'x + y - z' here x is total number of gerade orbital and y is total number of ungerade orbitals and z is total number of axial orbital in given above orbitals.

Correct answer: 1. Step 1: Note that because ICl and Br2 have similar molecular sizes and masses, their London dispersion forces are comparable in strength. Step 2: However, ICl consists of two atoms with different electronegativities, making it a polar molecule with dipole-dipole intermolecular attractions. Br2 is homonuclear and completely non-polar, having only dispersion forces. Step 3: The additional dipole-dipole forces in ICl require more energy to overcome, resulting in a significantly higher boiling point. Thus, option (c) is correct.
