In which of the following molecules is there a Y-X-Y angle (where X = N, P, S and Y = H, F) that is close to or equal to 90° (i.e. <95°): PF5, PH3, NH3, and SF6. PF, only NH3 only SF6 only SF6 and PFs only SF, PFs and PH3 only

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 ne…

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 t…

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 forma…
