Chapter 8, Problem 8.53SP

A potential replacement for the chlorofluorocarbon refrigerants that harm the Earth’s protective ozone layer is a compound called E143a, or trifluoromethyl methyl ether, ${\text{F}}_{\text{3}}{\text{COCH}}_{\text{3}}$ .Draw an electron-dot structure for ${\text{F}}_{\text{3}}{\text{COCH}}_{\text{3}}$ , and predict the geometry around both the carbons and the oxygen.
