Aromatic aldehyde

Aromatic aldehydes are useful in numerous applications, especially as flavors, fragrances, and pharmaceutical precursors.
Now, aliphatic aldehyde and aromatic aldehyde are two broad classes of the aldehydes. The difference in the interaction between the carbon and hydrogen atoms. In the aliphatic aldehyde the bonds present between the carbon and hydrogen are weak so, they can be easily broken and are quite reactive while in aromatic aldehydes the carbon atoms are arranged in the form of a flat ring therefore the interaction between carbon atoms are stronger and difficult to break and are less reactive also.
