Chapter 8, Problem 90IL

(a)

Interpretation Introduction

Interpretation:

The molecule, methylacetamide is polar or not has to be identified.

Concept Introduction:

The unequal distribution of shared electrons caused by differences in electronegativity between bonded atoms is called bond polarity.

A molecule is non-polar, if the charge distribution is symmetric and a molecule is polar if the charge distribution is asymmetric.

I a molecule us symmetric in shape it is said to be non-polar. If a molecule is not regular, it is said to be polar.

(b)

Interpretation Introduction

Interpretation:

The expected position of positive and negative charges in methylacetamide has to be predicted and also identify whether the electrostatic potential surface confirm the prediction.

Concept Introduction:

Electrostatic potential surface or maps are known as molecular electrical potential surfaces, that illustrates the charge distributions of molecules three dimensionally.
