successfully perform a dehydration of a 2-butanol and a dehydrohalogenation of 2-bromobutane to form the products 1-butene‚ trans-2-butene‚ and cis-2-butene. It was found that a dehydration of 2-butanol yielded 4.6% 1-butene‚ 67.3% trans-2-butene‚ and 28.1% cis-2-butene‚ and a dehydrohalogenation of 2-bromobutane yielded 19.1% 1-butene‚ 69.9% trans-2-butene‚ and 11.0% cis-2-butene.

chair boat The second type of stereoisomerism is geometric isomerism which is common in alkenes. Geometric isomers differ in physical properties such as melting points and boiling points. ex. cis (same side) trans (opposite side) For alkenes where cis-trans configuration does not apply‚ the geometry of the alkene may be designated by E (entgegen‚ opposite) or Z (zussamen‚ together). This is applied by determining
