CHEM 312 Problem Set 3 1. Name the following isomers of MTBE: O 2-methoxy-2-methylpropane O 1-ethoxypropane O 2-ethoxypropane O 2-methoxybutane O 1-methoxybutane OH pentan-1-ol OH pentan-2-ol OH pentan-3-ol OH 3-methylbutan-1-ol OH 3-methylbutan-2-ol HO 2-methylbutan-2-ol OH 2,2-dimethylpropan-1-ol 2. Label the following as a) soap; b) anionic detergent; c) cationic detergent; d) nonionic detergent; e) not a soap or detergent S O - Na + O O anionic detergent OH not soap/detergent OH OH OH nonionic detergent O + Na - O N + Cl - soap not soap/detgt

Unformatted text preview: OH OH HO OH HO O O 1 2 3 4 II. Same ranking for all properties: OH NH NH 2 + Cl-1 2 3 4 III. H 2 O solubility: ionic>H-bonding, then smaller>larger (better O/C ratio). MP, BP: ionic>H-bonding, then larger>smaller (more London forces). Be sure to understand this! OH O O-Na + O OH O O-Na + O bp, mp: 2 H 2 O sol: 1 bp, mp: 3 H 2 O sol: 3 bp, mp: 3 H 2 O sol: 4 bp, mp: 1 H 2 O sol: 2 IV. Some subtle differences between the first and last molecule.
