Concept explainers
(a)
Interpretation: The three-dimensional shape and Lewis structure of should be determined
Concept Introduction:
- VSEPR theory: This theory was developed to predict the shapes of covalent molecules in which atoms are joined together with single covalent bond. According to this theory
- The electron pairs around the central atom in a molecule tend to stay in space as far as possible so that repulsive forces between electron pairs are minimum
- The geometry or shape of the molecule is determined by the orientation of electron pairs.
- The shape of the molecule is regular if the electron pairs around the central atom are shared pairs only because they exert repulsive forces equally
- The shape are irregular if they have shared as well as lone pair around the central atom because they exert repulsive forces unequally.
- Lewis dot structure: The structure which shows the distribution valance electrons of all the atoms involved in bonding. This includes bonding electrons as well as lone pair of electrons.
