I'm doing work for my organic chem 2 class and it's been about three years since I did the first class in the series. I think I'm understanding the current material being presented but there are a couple of blanks in the middle that I think I'm missing out because lack of background knowledge.
This question is based on carbene addition to alkenes.
Two points I'd appreciate being clarified:
1. In (c), through what mechanism is there a carbene being formed to be able to attack the double bond on the cyclohexene? I'm assuming the third molecule in the equation reacts with tribromomethane to remove an H.
2. In general, the carbene attacks the double bond on the alkene to form a cyclic formation (epoxide?). When I was comparing my answers on chegg, I noticed that in (b) and (e), the carbene's carbon in the product is no longer bonded with I, while in (c), the carbene's carbon in the product *is* still bonded with the original two Br. Why is this?
