E) a cycloalkane with five or more carbons.

Question

Quizplus · Accepted Answer

An unsaturated hydrocarbon is a compound in which one or more carbon atoms have double or triple bonds, meaning that not all carbon atoms have four single bonds. Option A is incorrect because a hydrocarbon containing oxygen is called an oxygenated hydrocarbon. Option B is incorrect because a compound with all carbon atoms having four single bonds is a saturated hydrocarbon. Option D is incorrect because hydrocarbons are usually insoluble in water. Option E is incorrect because a cycloalkane cannot have double or triple bonds.
