4-dimethylaminopyridine (dmap; below) is an extremely useful molecule in organic chemistry. one professor here at osu often comments to graduate students when theirreaction isn’t working just to sprinkle a little dmap into their reaction. which nitrogen atom of dmap is most nucleophilic? use drawingsanda minimumamount of wordsto support your answer.

Nitrogen A would be more nucleophilicity (figure 1.)

Explanation:

In the DMAP molecule we will have 2 nitrogens label as "nitrogen A" and "nitrogen B". For nitrogen B we will have more steric hindrance due to the 2 methyls groups and the benzene ring. What will hinder the attack from this nitrogen (nitrogen B) to an electrophile. On the contrary, the attack of nitrogen A could easily occur.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
