Chapter 25

Individually, provide the Lewis structure for 1 -propanol and then predict which bond will be the shortest and what the \(\mathrm{C}-\mathrm{O}-\mathrm{H}\) bond angle will be. When all team members are done, compare answers and reach consensus.

Recall that the electronegativity of \(\mathrm{C}\) and \(\mathrm{H}\) are roughly the same, but that \(\mathrm{O}\) has a significantly higher electronegativity. For each type of compound (alkane, ketone, alcohol) predict whether or not the compound is expected to be polar or nonpolar.

For each type of compound below, indicate how the boiling point changes as the molecular weight of the compound increases: a) alkane b) ketone c) alcohol

Find an alkane, a ketone, and an alcohol with roughly the same MW (within \(5 \mathrm{~g} / \mathrm{mole}\) ). Rank these compounds in terms of relative boiling points.

Is the strength of intermolecular forces determined by the bond strengths within the individual molecules? Explain your reasoning.
