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

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
