Question

Draw eight possible constitutional isomers containing three membered cyclic ring with molecular formula C5H10O. Identify the classes of compounds for the isomers.

Answer 1

Answer: First calculate the degree of unsaturation present in given molecule.

Degree of unsaturation= (2n+2-H)/2.

n= number of carbon atom

H= number of hydrogen atom

Here molecular formula is C5H10O.

Degree of unsaturation= (10+2-10)/2=1.

So one ring is present made of three carbon or made of to carbon and one oxygen. So possible constitutional isomers is given below. But there more than eight constitutional isomers is possible.
