cis/trans isomers
« on: November 04, 2009, 10:56:14 AM »
Why are there cis-trans isomers on 2-butene but not in butane?
is it because of the double bond in the butene????
????

i think i can i think i can CHEM

Yes?  Can you define cis/trans for me?

is cis the same plane
and trans is on different planes...
im not too sure why it would be b/c of the dbl bond though

butane cannot have cis trans isomers as each carbon atom is bonded to 3 other atoms (hydrogen in this case). Basically only alkenes have geometric cis trans isomers

For further information:
Beside alkenes, cyclic structures also can have geometric isomers
(i.e. geometric isomer is another term for cis,trans isomers)
