WebPhenols have an -OH group attached directly to a benzene ring. In the substance normally called "phenol", there isn't anything else attached to the ring as well. We'll look at that first. … WebThe lone pair would be more stable in an sp2 orbital rather than a p orbital. Hybridization is a way to answer the OP's question. The C-H bond in benzene is $\ce{sp^2}$ while the C-H bond in ethylene is $\ce{sp^{2.2}}$, consequently the phenyl carbanion is more stable. If this question is reopened I will write more. $\endgroup$ –
