# What is the formula of cinnamic acid and how many isomers does this molecule have?

Dec 29, 2017

${C}_{6} {H}_{5} C H C H C O O H$

see below

#### Explanation:

trans- and cis- isomers

From now on I will change only the ${C}_{6} {H}_{5}$ molecule part.
And we get 5 more isomers.

NOTE:mistake $\to$ on the last example, the H atom on the second C-atom from the right is missing.
