Question
Boiling point trends - use table on next page and the internet What is the approximate increase in b.p. with addition of one carbon to an alcohol? What is the boiling point (°C) of ethylene glycol? What is the effect of branching on b.p.? List the strongest attractive force between molecules for each compound. Rank boiling points from highest (1) to lowest (4). (Remember that attractive forces have a larger effect on bp than branching, consider them first.) Force Bp rank CH3 H3C OH CH3 CH3 HO Why is the boiling point so high? CH3 H₂C Solubility At what pH range will (CH3CH2)2CHCF₂COOH, pka = 2, be soluble in water? Toxicity Search pubchem. ncbi.nlm.nih.gov for one of the alcohols in Figure 1. Click on Toxicity in the righthand column and scroll the data. What is the human oral or inhalation toxicity listed. CH3 Alcohol you chose Toxicity Calculate the volume of 80-proof ethanol ( 40 %) , for example vodka, that would have a 50% chance of killing you, if you were a rat, using your body weight in kg. (The density of vodka is 0.94 g/mL.) in ether? At what pH range will (CH3CH₂)2CHCF₂COOH (pka = 2) separate from C6H5COOH (pka = 5) in a liquid/liquid extraction? (one compound in the water layer and the other compound in the ether layer) It might help to draw the compound's structure at different pH's to see the formal charge on the molecule.
