Write an acceptable iupac name for the compound below. include 'cis' and trans' as part of the name when stereochemistry is illustrated.

These compounds are called stereoisomers. They have the same chemical formula, but differ in their geometric structural formula. The cis isomers have the same functional groups on the same side. Otherwise, the compound is in trans form. For example, the cis-trans isomers of 2-butene or but-2-ene are shown in the attached picture.

If a similar group is located on the same side of the double bond it is called -cis, but if the group is opposite it is called -trans

Further explanation

Isomers are two compounds that have the same chemical formula but different structural formulas

There is a grouping of isomers in Hydrocarbons, namely:

1. Structure isomer consisting of skeletal isomers, position isomers, and function isomers2. Stereoisomers consisting of geometric isomers and optical isomers

Geometric isomers occur because of differences in the direction of the groups in the molecule

Geometrical isomers are found in compounds that have double bonds such as alkenes and the two C atoms bind 2 different groups, so that if the location of the groups are exchanged the shape becomes different

If a similar group is located on the same side of the double bond it is called -cis, but if the group is opposite it is called -trans

Example:

Atomicity to 2 butenes. Where in cis-2 butene, both methyl groups are located on the same side whereas, in trans-2 butene, both methyl groups are opposite
