Question
Chapter 1, Problem 1.38AP
Interpretation Introduction
Interpretation:
Whether the given experimental fact provides a clue to the preferred dihedral angles in ethylene has to be predicted with an explanation.
Concept introduction:
The dipole moment is defined as the charge separation between two atoms in a covalent bond or between two ions in an ionic bond. It is used to determine the polarity of atoms or ions. If the value of dipole moment is zero, then the molecule is said to be non-polar, and if the value of dipole moment is not zero, then the molecule is said to be polar and possess permanent dipole moment.

Based on the electrostatic poten1ial map shown below. where do the neg-alive and positive charges lie in the molecule? Polarity: It is a well separation of electric charge leading to a molecule or chemical compounds having an electrical dipole moment. Generally the polar molecules must contain polar bonds due to a different in electronegative between the bonded atoms. The electrostatic potential map clearly to explain, the oxygen atom has more negative () charge and other side has less positive () charge, so this molecule is a more polar nature.arrow_forward
