I even have some family coming over this weekend. I'm excited because they've never really come to visit me. But I can't bring myself to clean my apartment and I have been struggling for the past week with this. Just thinking about it makes me want to take a nap. At least it's not that bad looking in here but still. I managed to clean one toilet bowl the other day and that was all I could bring myself to do.
I actually did do that one time! It was a bit pricey but gave me some peace of mind. Sadly it's a bit too late in the week now otherwise that would have been a good idea lol!
It's an N-methyl group (one extra carbon attached to the nitrogen).
Love, your friendly neighborhood chemistry prof
Just to add some actual useful knowledge, amphetamines are a subset of psychoactive compounds called "phenethylamines," the effects of nearly all of which get more potent when you add a methyl group onto the nitrogen (often times as much as 10x more powerful, IIRC).
