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 is not recommended to obtain para -bromoacetanilide by bromination of aniline then acetylation?
Aniline is a benzene with an amine group attached to it. When you brominate aniline, since aniline is electron donating, it directs other substituents to the ortho and para positions. Therefore you will not only get para-bromoacetanilide. However if you just want para-bromoacetanilide, you should go through acetylation first because this changes the amine group on the aniline into an acetamido group which is very bulky and big, and also electron donating. Since it is so big, the bromine cant attach to the ortho positions because of the steric hindrance caused by the very bulky acetamido group and therefore you will get para-bromoacetanilide as your product.
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.
Why ortho chlorobenzoic acid is stronger than benzoic acid?
conjugatory effect
Which is more acidic ortho-nitro benzoic acid or ortho-methoxy benzoic acid?
orho methoxy benzoic acid is more acidic due to stability achieved due to chelation effect.
What is formula of aniline?
The chemical fomula of aniline is C6H7N.
Ortho effect on acidity of carboxylic acid?
ortho effect reduces acidity of carboxylic acid. It is due to steric hindrance at ortho position

What is ortho evra?
Ortho Evra is a birth control patch that is stuck to your skin. It has the same mode of action and mostly the same side effect profile as the birth control pill.
What is the difference between Aniline Point and Mixed Aniline Point?
There is no any such difference between Aniline point and mixed Aniline point . . . . .
Which is more acidic ortho-nitro benzoic acid or ortho-methoxy benzoic acid?
orho methoxy benzoic acid is more acidic due to stability achieved due to chelation effect.
What is formula of aniline?
The chemical fomula of aniline is C6H7N.
Why the electrophilic substitution reaction of haloarenes is oRtho and pera directing?
Because the +R effect of the haloarene, tends to oppose the -I effect, and hence the deactivation is lesser at the ortho and para positions, compared to any other position (like the meta position). So they tend to be o-p directing.
What is an aniline?
An aniline is an aromatic amine, synthesized by the reduction of nitrobenzene.
What brand of birth control pills have ortho tricyclen?
Ortho Tricyclen is made by Ortho.
What is the chemical formula of aniline hydrochloride?
The formula of aniline is C6H7N and the formula of ethanol is C2H5OH.
