2022 May TZ1 HL Chem Paper 2 Attempt 2

I got a bit tired at the end and was rushed, so I just want to clear up some speaking errors I made. The mechanism we did with iodomethane was SN2 and not SN1. And the nitronium ion is an electrophile and not a nucleophile. I made some other errors too I’m sure. Just wanted everyone to know. Welcome redditors. I will be providing solutions to the M22 HL Paper 2. I am not going to teach my way through it, but I will explain things as I do them.
