Isomers are molecules that have the same molecular formula but have different structural formulas. The atoms in the molecular formula C₃H₈O can be arranged in 3 different structural formulas. Try drawing these 3 structural formulas. Keep in mind that, unless they are charged, carbon atoms form 4 bonds, oxygen atoms form 2 bonds and hydrogen atoms can only form 1 bond. Use dashes to connect the atoms together as bonds. [answer]
