Question

Draw the possible isomers of the compound with the molecular formula ${\mathrm{C}}_3{\mathrm{H}}_6\mathrm{O}$ and also give their electron dot structures.

Answer 1

Isomers:

Isomers are compounds that have the same empirical formula but differ in the arrangement of atoms in the compound

Isomers of ${\mathrm{C}}_3{\mathrm{H}}_6\mathrm{O}$

• Possible arrangement of atoms can be:

$\underset{\mathrm{Propanal}}{\mathrm{H}-\underset{\underset{ }{\overset{|}{H}}}{\overset{\underset{|}{H}}{C}}-\underset{\underset{ }{\overset{|}{H}}}{\overset{\underset{|}{H}}{C}}-\underset{ }{\overset{\underset{\parallel }{O}}{C}}-\mathrm{H}}$ and $\underset{\mathrm{Propanone}}{\mathrm{H}-\underset{\underset{ }{\overset{|}{H}}}{\overset{\underset{|}{H}}{C}}-\underset{ }{\overset{\underset{\parallel }{O}}{C}}-\underset{\underset{ }{\overset{|}{H}}}{\overset{\underset{|}{H}}{C}}-\mathrm{H}}$

• Dot structure of the Propanal and Propanone

So, The compound with the chemical formula ${\mathrm{C}}_3{\mathrm{H}}_6\mathrm{O}$ has two isomers named Propanal and Propanone.
