Hi there! For 7, this reaction is a conjugated hydrohalogenation which involves a production of 1,4-disubstituted and 1,2-mosubstituted product. The mechanism of 1,4 product requires a less stable intermediate which means it requires a very high energy intermediate. Check out Johnny's video on Conjugated Hydrohalogenation here:

For 8, oxygen there has partial positive charge because it exceeds its bonding preference of 2.

Hope that helps!

  • For 7, wouldn't the ring structure be the most unstable since it has sp3-sp3 bonds and no sp2-sp3 bonds? Why doesn't the ring one have the most unstable structure? For 8, isn't the oxygen is breaking a bond with the H though and then getting a lone pair of e's making oxygen partially negative? Lauren commented 11 months ago
