WebTest for Alkenes Alkenes are called unsaturated compounds. They contain at least one carbon-carbon double bond which displaces two hydrogen atoms and so do not have the maximum number of hydrogen atoms per carbon atom. Alkanes on the other hand are called saturated compounds. WebTesting alkane & alkene with bromine water Share Watch on Note: I suspect that the two compounds are cyclohexane and cyclohexene. Cyclohexane has a ring of 6 carbon atoms with 2 hydrogens attached to each. Cyclohexene also has a ring of 6 carbon atoms, but this time there is a double-bond in the ring. birthday testimonials
