WebGroups: Ortho–Para Directors Alkyl substituents are electron-donating groups and they are activating groups. They are also ortho–para directors. Groups that have an unshared electron pair on the atom attached to the aromatic ring, such as amino, hydroxyl, alkoxyl, and amides or esters with the oxygen or nitrogen directly WebEither ortho and para products or meta product is predominantly formed. It has also been observed that this behaviour depends on the nature of the substituent already present in …

WebFeb 28, 2024 · If the relative yield of the ortho product and that of the para product are higher than that of the meta product, the substituent on the benzene ring in the monosubstituted benzene is called an ortho, para directing group.

WebAtoms or groups that make the benzene molecule more reactive by increasing the ring's electron density are called activating groups. Activating groups serve as ortho‐para directors when they are attached to a benzene ring, meaning that they direct an incoming electrophile to the ortho or para positions. WebSome groups are “ ortho / para directors”. The other group reacts to make mostly meta -substituted products. Here may be small amounts of ortho – and para – products, but these groups are best described as “ meta -directors”. These regiochemical effects are very closely related to the activating and directing effects we have already seen. WebMeta directing group: The groups which direct the incoming group to meta position are called meta directing groups. Some examples of meta directing groups are –NO 2, –CN, –CHO, –COR, –COOH, –COOR, –SO 3 H, etc. Let us take the example of nitro group. Nitro group reduces the electron density in the benzene ring due to its strong ... crystal luedtke
