Title: isotope of butene
Post by: monokekie on May 26, 2009, 04:23:31 pm

hey guys,

Just wondering how many structural isomers does butene have?

i got, but1ene, but2ne .... but not quite sure about cyclobutane (which is C4H8 as well)....

could anybody please give me some hint ?

tyty in advance!

When in doubt, draw it out! Cycloalkanes have the same formula as alkenes CnH2n

and methyl-cyclopropane (btw it's cyclobutane, not cyclobutene, cyclic alkenes are C_n H_(2n-2)
