Chemistry of Alkenes - Lab Report Example Although there is the presence of the =C-H stretch, that shows presence of pentene as well. However, the wavenumbers corresponding to C-F, C-O, C-N and even aromatic =C-H stretch indicates that there is contamination. The Belstein test is a test for alkyl halides. The green flame is indicative of the presence of chlorine in the liquid, thus implying unreacted 3-chloro-3-methylpentane. The bromine test and potassium permanganate test are qualitative tests for alkenes. The color of the solution changed from brown to colorless, indicating the presence of an alkene in the product (bbc.co.uk, n.d.). The brown precipitate appearing in the solution after the permanganate test also indicates the presence of an alkene functional group (chemguide.co.uk, 2010). 4. Three unique alkene products are possible for the dehydrogenation reaction of 3-chloro-3-methylpentane. Two of the alkenes are related as E and Z isomers. Draw a Newman projection of the reactive conformation that produces the E isomer and a Newman projection that produces the Z isomer assuming an E2 mechanism for
