How many constitutional isomers does C5H10 have? Please draw all of them.

Question

The molecule C5H10 can exist in numerous architectures that are all constitutional isomers. They are constituted of the same things but the connectivity of atoms in each differs. This is important as the physical properties of the compounds are all similar but not the same. Distinguishing, identifiying, and drawing the isomers of a given chemical formula is an important ability used in Organic I.

The job is to determine how many distinct compounds exist with this formula and to draw their 2D structures. (Ignore stereochemistry and sterochemical isomers for this problem.)

Answer 1

5 alkenes

5 cycloalkanes

for a total of 10 constitutional isomers.
