How to use in-sentence of “alkenes”:
– When a catalyst is added to the reaction, or it is heated under pressure, unsaturated alkenes link together, when the double bond partially breaks.
– The names of alkenes always end with -ene.
– Methene is not possible as alkenes require a carbon-carbon double bond and methane only has one carbon atom.
– The physical properties of alkenes are comparable with those of alkanes.
– The abundant and diverse products from coal and petroleum led to Ziegler-Natta, Fischer-Tropsch processFischer-Tropsch, hydroformylation catalysis which employ CO, H, and alkenes as feedstocks and ligands.
– The two “trans” alkenes react head-to-tail, and the isolated isomer is called “truxillic acid”.
