A substituent (-X) is said to be an … WebCl are ortho,para-directing. Similarly, we could not prepare p-nitrobenzenesulfonic acid directly because both the nitro and sulfonic acid substituents are meta-directing. 4 Only two such contributors are possible: Any additional resonance contributors disrupt the benzenoid structure in the “left” ring.
Chlorobenzene is o, p – directing in electrophilic substitution ...
WebDec 8, 2024 · Some common ortho para directing groups are –Cl, -Br, -I, -OH, -NH2, -CH3, -C2H5. The group which directs the second incoming group to the meta position, is called a meta-director. For example, alkylation of nitro benzene gives m-alkylnitro benzene as major product. Which of the following is an ortho para directing but deactivating? WebAnd ortho, para-directing because they direct the new substituent to the ortho or para positions relative to the substituent obviously. So if you did an electrophilic substitution on isopropylbenzene (or cumene), then the ortho and the para products would be considered the major products, while the meta product (which is still produced) would ... c言語 配列 ポインタ 違い

In general para isomera are thermodynamically more stable than ortho isomers (except in cases when ther is hydrogen bonding in ortho isomer). There are several reasons:- 1. Steric hindrance makes para isomer more stable. 2.Benzene substituents rotate and change thier plane due to steric hindrance. It stops delecolaization of lone pair ... c言語 配列 メリット
