For an organic synthesis class I have to do a synthesis of 7-Methoxytetrazolo[1,5-a]quinoline-4-carboxaldehyde. To be honest I don't remember at all how to name heterocyclic compounds. I don't get the tetrazolo[1,5-a]quinoline part and why does 4-carboaldehyde is at position 4 if the methoxy group is at position 7.
I attached a screenshot of the compound that I drew on chemdraw.
Help this poor soul, please :c
