Isomer geometri bukan hanya pada senyawa rantai lurus saja loh. For example, in the alkenes, two versions of 2-butene exist.551.Senyawa ini adalah alkena paling sederhana yang memiliki isomerisme cis/trans (dikenal pula sebagai isomerisme-(E/Z)); yaitu, senyawa ini hadir sebagai dua isomer geometris cis-2-butena ((Z)-2-butena) dan trans-2-butena ((E)-2-butena). Perhatikan contohnya: 1,2-diklorosikloheksana: cis-1,2 E/Z will work – even when cis/trans fails. Although the H–H contact can be linked with smaller, relative to trans-, rotational energy barrier in cis-2-butene, we have proven that to rationalize this phenomenon one must account for changes in interactions between various fragments that constitute the entire molecule.

IUPAC Standard InChIKey: DSDHFHLZEFQSFM-ARJAWSKDSA-N. Senyawa alisiklik juga memiliki isomer geometri cis dan trans loh. Monoisotopic mass 88. And in that sense trans-2-butene is more stable because it avoids the steric hindrance that cis-2-butene encounters. Start with the left hand … This structure is also available as a 2d Mol file or as a computed 3d SD file. Hope that helps. Consider the alkene with the condensed structural formula CH 3 CH=CHCH 3.

These two compounds are cis-trans isomers (or geometric isomers), compounds that have different configurations (groups permanently in different places in space) because of the presence of a rigid structure in their molecule. But if we're comparing the stability of both molecules then we're inspecting which one is more likely to be formed in a reaction. Therefore, there are two different ways to construct the 2-butene molecule. Isomer ini hanya terjadi pada senyawa yang memiliki ikatan yang kaku dengan dua sisi berlainan dan, biasanya terjadi pada senyawa alkena.
