4short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is direction of delocalisation?Show answer
For acidity, the negative charge of the phenoxide ion delocalises into the ring; for ring activation, the oxygen lone pair delocalises into the ring. State which effect you mean.
What is catalyst for phenol bromination?Show answer
No halogen carrier is needed for phenol (the ring is activated); requiring is the answer for benzene, not phenol.
