Chapter 3.7, Problem 3.18YT
(a)
Interpretation Introduction
Interpretation: The Lewis structure of
Concept Introduction:
Lewis structure: The bonding between atoms in a molecule satisfies the octet rule of valence electrons and the lone pairs also exist in the molecule. The electron is represented as dot.
Geometry: The spatial arrangement of atoms or group of atoms around the central atom defines the geometry of the compound. The geometry can be determined by constructing Lewis structure and VSEPR model.
Hybridization: The concept of mixing atomic orbitals into new hybrid orbitals that possess different shapes, size, and energy than the constituent atomic orbitals.
- Ø Lone-pair electrons are valence electrons that are not used in bonding.
- Ø A proton is positively charged hydrogen ion. A hybrid ion is a negatively charged hydrogen ion.
- Ø Formal charge = the number of valence electron – the number of electrons the atom has to itself (the entire lone pair electron and one – half of the bonding electrons).
- Ø Lewis structure indicates which atom is bonded together and show lone pairs and formal charge.

Learning Goal:
When covalent compounds, such as water (H₂O), form covalent
Donds, they share valence electrons. A Lewis dot structure or
electron dot structure is a drawing that represents chemical
bonds between atoms as shared or transferred electrons, where
the valence electrons are represented as dots. For example,
notice the Lewis structure of NC13 (Figure 1). When a pair of
a bond.
electrons is shared between two atoms, a line is drawn to indicate
