WebExplanation: The cis-trans definition is unambiguous only when you have two different groups on one of the alkene carbons and the same two groups on the other carbon, as in but-2-ene. Then the two identical methyl groups are either cis or trans to each other, and the two identical hydrogen atoms are either cis or trans to each other. WebEthenyl is named before methyl because e comes before m, and ene is named before yne because e comes before y. 2. The numbering of polycyclic compounds is a bit complicated. Let us take a simple example. The compound known as "hexahydroindan" consists of a cyclononane ring with a bond between C-1 and C-5. philippine underground river
