WebAll right, so now all we have to do is go from benzene to bromobenzene And, of course, that's really simple. It's just a bromination reaction again. So we have our bromine, and … WebCycloalkanes are very similar to the alkanes in reactivity, except for the very small ones, especially cyclopropane. Cyclopropane is significantly more reactive than what is expected because of the bond angles in the ring. Normally, when carbon forms four single bonds, the bond angles are approximately 109.5°.
WebZaitsev's rule states that: when a reaction forms an alkene, and several possibilities exist, the more (or most) stable isomer is the one which predominates. Your task is to convert 2-bromobutane to 1-butene in highest yield. Which reagents …
