WebThe cis/trans or E/Z isomers formed by alkenes aren't the only example of stereoisomers. To understand the second example of stereoisomers, it might be useful to start by considering a pair of hands. For all practical purposes, they contain the same "substituents" four fingers and one thumb on each hand. If you clap them together, you will find ... WebSquare planar and octahedral complexes with two pairs of different ligands exhibit cis - trans isomerism An example of a square planar complex with two pairs of ligands is the anti-cancer drug cis-platin Whereas cis- platin has beneficial medical effects by binding to DNA in cancer cells, trans- platin cannot be used in cancer treatment WebThe 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. crystalis cheat codes
