D₂ a Given that the spatial requirement of a lone pair is greater than that of a bond pair, explain why XeF2 has a linear molecular structure and not a bent one. O The four lone pairs of XeF2 occupy the equatorial positions. The angles between lone pairs are 60°, so there is less lone pair/lone pair repulsion with this arrangement. O The two lone pairs of XeF2 occupy the equatorial positions. The angle between lone pairs is 180°, so there is less lone pair/lone pair repulsion with this arrangement. O The two lone pairs of XeF2 occupy the equatorial positions. The angle between lone pairs is 60°, so there is less lone pair/lone pair repulsion with this arrangement. O The three lone pairs of XeF2 occupy the equatorial positions. The angles between lone pairs are 120°, so there is less lone pair/lone pair repulsion with this arrangement. Submit
Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
