Indicate whether or not each of the structures is considered to be aromatic. Both compounds are six atom rings arbitrarily numbered starting from the top and moving clockwise. Both have a carbon in position 1 that is bonded to an N H 2 where the nitrogen has a lone pair. Carbon 1 is double bonded to nitrogen in position two. This nitrogen has a lone pair. Position 3 is a carbon that is double bonded to an oxygen and the oxygen has two lone pairs. Position 5 and 6 is an alkene. Both compounds have a nitrogen in position 4, but the nitrogen in compound A is bonded to one methyl and has a lone pair on the nitrogen, whereas the nitrogen in compound B is bonded to two methyls and has a positive charge. Which is true
