WebOct 29, 2014 · Since there are 18 isomers, you must use a systematic process. First, if you replace the Cl with H, the formula becomes C₄H₈. An alkane would have the formula C₄H₁₀, so the compound may contain a double bond or a ring. Draw all possible C-4 alkenes containing 4 C atoms in a row. Draw all possible C-4 alkenes containing 3 C atoms in a row. WebGeometric isomers are identified with the appropriate cis- or trans- prefix. Small ring compounds are unstable due to ring strain, which is the result of the small bond angles required to maintain the structure. The most severely strained compounds are cyclopropane and cyclobutane.
