Ethanol, the alcohol found in alcoholic beverages, has the same formula as the ether of Problem 5.78. However, it has a different structure, in which only one carbon atom is bound to the oxygen atom. Starting with dot diagrams for the atoms, draw a dot diagram for the ethanol molecule. Indicate the total number of bonding pairs and lone pairs of electrons. Also comment on the fact that one form of C₂H₆O is a solvent (poisonous) but another form is drinkable and what this says about the role of structure in determining the chemical properties of a molecule.

Data from Problem 5.78

Ethers are compounds of C, H, and O that are often used as solvents. One particular ether molecule has the formula C₂H₆O. The structure is such that both carbons are attached to the oxygen atom, and there are no O—H bonds. Starting with dot diagrams for the atoms, draw a dot diagram for this ether molecule. How many bonding pairs does the molecule have? How many lone pairs?
