NettetA carboxylic acid attached you a benzene ring gets the name benzoic acid. This is actually called a methoxy group. Back when we talked about ethers, we learned that ethers can be named with an alkoxy substituents. Those would be like an ether, ROR, methoxy. If you see methoxy, that's called an anisole. Like I said, some of these are getting weird.
NettetWith benzene: . . . and methylbenzene: These reactions destroy the electron delocalisation in the original benzene ring, because those electrons are being used to form bonds with the new hydrogen atoms. Although the reactions are exothermic overall because of the strengths of all the new carbon-hydrogen bonds being made, there is a high ... create birdbathNettetAnother way of adding hydrogen to the benzene ring is by treatment with the electron rich solution of alkali metals, usually lithium or sodium, in liquid ammonia.
