QUIZ 1. Which is the correct way to describe an ether? a. RCOOR’ b. ROR’ c. RCOR’ d. RCOH Answer: b. The basic structure of the ether molecule is ROR’, in which two side chains are connected by an oxygen molecule. 2. Which of the following is the correct name for an ether, according to the IUPAC nomenclature? a. Ethoxy-methane b. tert-butoxy-ethane c. Isopropoxy-ethane d. Methoxy-ethane Answer: d. The only correct naming structure for an ether comes when the shorter alkane is listed as the oxy group or alkoxyl side chain and the longer alkane is considered the parent compound. 3. What can be said about the boiling point of ethers? a. It decreases with molecular mass and approaches that of alcohols of the same size. b. It decreases with molecular mass and approaches that of alkanes of the same size. c. It increases with molecular mass and approaches that of alcohols of the same size. d. It increases with molecular mass and approaches that of alkanes of the same size. Answer: d. Boiling point will increase with molecular mass in all organic molecules; as there are no hydrogens attached to the oxygen
