Chapter 8, Problem 8.57SP

Interpretation Introduction

Interpretation:

The electron-dot structure for ${\text{F}}_3{\text{COCH}}_3$ and geometry around both the carbons and the oxygen should be identified.

Concept introduction:

To draw electron dot structure of trifluoromethyl methyl ether, you have to get aware about the valence electron of carbon, fluorine and oxygen.

The valence shall electron pair repulsion (VSEPR) theory is a simple and useful way to predict and rationalize the shape of molecule. The angle between atoms can also be find out.

To determine:
Draw an electron dot structure of ${\text{F}}_3{\text{COCH}}_3$ and predict the geometry around both the carbon and oxygen.
