I am trying to draw a constitutional isomer for the compound CH3CH=CHCH3 but I am having some trouble.
H-C-C=C-C-H I drew the first compound like this with more hydrogens on the Cs. How could I draw another strucutre?
Have you heard of cis-trans isomerism?
To draw a constitutional isomer for the compound CH3CH=CHCH3, you need to rearrange the atoms while maintaining the same molecular formula. Here's how you can do it:
Start by identifying the carbon atom that is directly bonded to more than one other atom. In this case, it is the central carbon atom bonded to two hydrogen atoms and two other carbon atoms.
To create a constitutional isomer, you can rearrange the connection of atoms around this central carbon atom. One possible arrangement is to move one of the methyl groups (CH3) from the terminal carbon to the central carbon:
H-C-C-C=C-H
In this isomer, the central carbon atom is now bonded to three hydrogen atoms and one methyl group, while the terminal carbon atom is bonded to one hydrogen atom and one carbon atom.
Remember, constitutional isomers have the same molecular formula but different connectivity of atoms.
