Concept explainers
Interpretation: The Lewis structure and shape of the given compound, the hybridization of the central atom and the resonating structure that has formal charge close to zero is to be identified.
Concept introduction: The Lewis structure represents all bonding and non-bonding electrons surrounding the atoms involved in a molecule. A molecule exhibits a particular geometry in space considering the steric hindrances of the bond pairs and the lone pairs of electron.
Resonance structures are different forms of a molecule in which the chemical connectivity of the atoms in a molecule is same but there distribution of electrons is different.
The formal charge is calculated by the formula,
To determine: The Lewis structure and shape of the given compound, the hybridization of the central atom and the resonating structure that has formal charge close to zero.
