Why is -NHCOCH3 a less powerful ortho para-directing group than -NH2?

-NH2 has a very good isomer effect that activates o,p
-NHCOCH3 has 2 isomers one who activates o,p and one who deactivates the o,p

Why nitro group is formed on ortho and para position?
orientation of incoming Nitro group is destined by already present group on benzene ring . if already present group is electron donating group, it will promote electron density at ortho and para position and , therefore, nitro group is formed on ortho and para position.
What is ortho meta and para in benzene?
ortho-para in benzene is meaningless these positions are for monosubstituted benzene. Meta is positions 3 and 5. Ortho is position 2 and 6 with relation to already attached group, para is 4 (opposite) to attached group.
Activating and deactivating group of Ortho para and meta director groups Explain?
You can either deactivate or activate the group of Ortho para and Meta director groups depending with your preference.
What is ortho effect in aniline?
the ortho effect operates due to position of substituted group in ortho position. it increases the steric repulsion in 'amino' grup of aniline there by decreasing its basicity ,i.e tendency to accept proton.
Why halogens that is deactivate group attack to ortho and para position?
Because of mesomeric effect, the electron density on the ortho and para positions for the aromatic ring is more.
What are the examples of Ortho and para directing group and mata directing group?
Electrophilic Aromatic Substitution is an example of Ortho and para directing group and meta directing group.
Why nitro group is formed on ortho and para position?
orientation of incoming Nitro group is destined by already present group on benzene ring . if already present group is electron donating group, it will promote electron density at ortho and para position and , therefore, nitro group is formed on ortho and para position.
Why methyl attached to benzene is ortho-para director group?
This group attached to benzene ring acts as the ortho-para directing group due to Hyperconjugation.
What is ortho meta and para in benzene?
ortho-para in benzene is meaningless these positions are for monosubstituted benzene. Meta is positions 3 and 5. Ortho is position 2 and 6 with relation to already attached group, para is 4 (opposite) to attached group.
Activating and deactivating group of Ortho para and meta director groups Explain?
You can either deactivate or activate the group of Ortho para and Meta director groups depending with your preference.
What is ortho effect in aniline?
the ortho effect operates due to position of substituted group in ortho position. it increases the steric repulsion in 'amino' grup of aniline there by decreasing its basicity ,i.e tendency to accept proton.
Why halogens that is deactivate group attack to ortho and para position?
Because of mesomeric effect, the electron density on the ortho and para positions for the aromatic ring is more.
Salicylic acid is ortho para directing group or meta directing group?
salicytic acid is a ortho para directing group ....however check up on that ...i am not completely certain .. Actually, it is a meta-directing group, because of the carboxylic acid functional that the salicylic acid contains. Hope that was helpful.
Why is only 4-bromoacetanilide created mainly from a bromination of acetanilide?
The Acetanilide is a benzene with a acetamido group attached to it. The acetamido group is electron donating and therefore it directs other substituents to the ortho and para positions. The acetamido group is also a very large group and the ortho position is right besides the acetamido group. This creates steric hindrance from bromine from getting to the ortho position and therefore only para-bromoacetanilide or 4-bromoacetanilide is created mainly from a bromination of acetanilide.
Why nitroso in nitrosobenzene deactivating yet ortho para directing?
NO-group acts exactly as halogens because of long pair on nitrogen. This pair stabilizes ortho-para intermediates.
What are the differences between ortho hydrogen and para hydrogen?
Positioning around a benzene ring relative to the major functional group. Para is opposite, ortho is next to, meta is in between.
What do you mean by the donor and acceptor ions?
Donor group are ortho-para directory groups that means increases in pai density of ortho para directory. Adaptor group meta directing groups that means increases in pai density of meta directing groups.
