Hello,

So basically I'm not very experienced in chemistry and need a bit of help. I'm stuck on a few questions and don't really understand them, so if any of you guys could, please answer and explain them and possibly give me any resources that cover this material effectively, preferably videos?

Below are the questions, you don't have to answer them just direct me to sources that can help me answer them or explain how to approach them. Also, I watched Khan Academy and other videos but none of them explain how to deal with more complex molecules like these (at least to me they are complex).Thank you!

It is a forum rule that you must show your attempt before we can help you.  IMO you have begun the process, but you haven't cleared the bar yet. I will give you a hint.  For number 2, treat the double bond as the nucleophile.  There are two possible intermediates, and each one has a formal +1 charge on one carbon atom.  For number 1, do you know what the definition of a chirality center is?

For the addition to alkenes:

Start with the first step in the mechanism (easily found online with a quick google search if you don't know it already).

Which carbon center would the first intermediate be the most stable on?
