WebPhenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. The more stable the ion is, the more likely it is to form. ... an oxygen substituent enhances the reactivity of the ring and favors electrophile attack at ortho and para sites. It ... WebThe meaning of PARA-AMINOPHENOL is the para isomer of aminophenol —written systematically with italic para- or p-.

WebTake phenol, add N a X + C H X 2 = C H − C H X 2 X − (you may use lithium instead of sodium--easily prepared from C H X 2 = C H − C H X 2 − X ). You will get P h − O − C H X 2 − C H = C H X 2 Heat it, the group migrates to ortho. Repeat, and now you have a phenol with two C H X 2 = C H − C H X 2 − groups at each ortho position. Now nitrate. Webp-cresol: pKa = 10.26 The phenoxide ion (shown above) has resonance structures with negative charges at the ortho and para positions. Attaching an electron-donating group, such as methyl, to these positions destabilizes the phenoxide ion, and thus makes the phenol less acidic. ulster phd scholarship
