WebClassify the given molecules by whether the substituent group is ortho-/para- or meta-directing in aromatic substitution reactions. Ortho- and para-directing Meta-directing Answer Bank C,H,COOH CHỤC … WebClassify the following groups as ortho, para or meta directing when present on benzene nucleus. (i) −CH 3, (ii) −NH 2, (iii) −NO 2, (iv) −COOH, (v) −OH, (vi) −SO 3H, (vii) −X (halogen), (viii) −OCH 3, (ix) −CHO, (x) −CN. Hard Solution Verified by Toppr (i), (ii), (v), (vii) and (viii) are o− and p−directing groups.
The –COOH group in benzene ring is: (A) ortho directly …
WebOrtho/para directors. Groups with unshared pairs of electrons, such as the amino group of aniline, are strongly activating and ortho/para-directing by resonance. Such activating groups donate those unshared electrons to the pi system, creating a negative charge on the ortho and para positions. These positions are thus the most reactive towards ... WebOrtho-para directing group: As discussed earlier, these groups direct the electrophilic attack on “ortho” and “para” positions. All activating groups are “ortho-para” directors, for example –NH 2, –NHR, –NHCOCH 3, –OCH 3 ,–CH 3, –C 2 H 5, etc. hand foot syndrome ctcae

WebOverreaction of Aniline. Arylamines are very reactive towards electrophilic aromomatic substitution. The strongest activating and ortho/para-directing substituents are the amino (-NH 2) and hydroxyl (-OH) groups.Direct nitration of phenol (hydroxybenzene) by dilute nitric acid gives modest yields of nitrated phenols and considerable oxidative decomposition to … WebJul 19, 2024 · The main point to remember here is that electron-donating groups direct substitution to the ortho and para positions, while pi electron-withdrawing groups direct substitution to the meta position. To clarify what is meant by electron-donating and electron-withdrawing substituents: Any substituent whose first atom (the one that's attached to the ... WebActivating groups (ortho or para directors) When the substituents like -OH have an unshared pair of electrons, the resonance effect is stronger than the inductive effect which make these substituents stronger activators, since this resonance effect direct the electron toward the ring. In cases where the subtituents is esters or amides, they are ... bushard and bolsa
