Cis-2-butene and trans-2-butene are geometrical isomers where trans-2-butene is more stable than cis-2-butene as the former has a lower steric strain. Alkynes: Alkynes are unsaturated hydrocarbons containing C≡C triple covalent bonds in their molecules.

WebCis-Trans Isomers -a particular example of stereoisomers -cycloalkanes can exist as cis-trans isomers -different 3D geometries possible because rotation about their C-C bonds cannot take place -can differentiate between top and bottom faces of structure Trans Different planes, same connectivity Cis Same face Conformation WebCorrect options are C) and D) Cis-trans isomers are stereoisomers, that is, pairs of molecules which have the same formula but whose functional groups are rotated into a … WebWe call these “cis” (same side) and “trans” (opposite sides). We focus on one of these, cis-1,3-dichlorocyclohexane. And for now, we will just look at hexagon structural formulas, leaving the question of conformation for later.
