Chapter 10, Problem 154SAE

Interpretation Introduction

Interpretation:

The concept map that shows the connections between Lewis dot structures, shapes of the molecules and the polarity should be constructed.

Concept introduction:

The Lewis structures are the diagrams that are used to show the bonding between various atoms in a covalent molecule and the number of lone pairs present in that molecule. These are also known as Lewis dot diagrams, electron dot diagrams, Lewis dot structures or Lewis dot formula. These are used to predict the geometry, polarity, and reactivity of covalent compounds.

The molecular shape is the three-dimensional arrangement of atoms in the molecule. It depends on the bond pairs as well as lone pairs.

The polarity refers to the separation of electric charge that leads to some electric dipole moment in the molecule. It arises due to the difference in the electronegativity between the bonded atoms. More the electronegativity difference between the atoms, higher will be the dipole moment and therefore high polarity.
