The ortho effect in aniline refers to the increased reactivity or stability of a molecule due to the presence of substituents on the ortho position of the aromatic ring. In aniline, the ortho effect can influence the rate of reactions or the properties of the molecule.

Nitration of aniline with nitrating mixture gives m-nitro-aniline?
In the nitration of aniline with a nitrating mixture, the electrophilic attack of the nitronium ion occurs at the ortho and para positions due to the activating effect of the amino group. The major product obtained is m-nitroaniline due to steric hindrance that prevents substitution at the ortho position.
Why is not recommended to obtain para -bromoacetanilide by bromination of aniline then acetylation?
Bromination of aniline can result in the formation of multiple brominated products due to the presence of ortho and para directing groups on the aromatic ring. This can lead to side reactions and impurities in the final product. It is more efficient and direct to start with the para-substituted derivative to avoid these issues.
Why the electrophilic substitution reaction of haloarenes is oRtho and pera directing?
Haloarenes are ortho-para directing because the sp2 hybridized carbon bonded to the halogen has a partial positive charge, which stabilizes the negative charge that forms at the ortho and para positions due to resonance. This resonance effect makes the ortho and para positions more reactive towards electrophilic substitution compared to the meta position.
Why ortho chlorobenzoic acid is stronger than benzoic acid?
Ortho chlorobenzoic acid is stronger than benzoic acid due to the electron-withdrawing effect of the chlorine atom. This increases the acidity of ortho chlorobenzoic acid by stabilizing the conjugate base through delocalization of the negative charge. In contrast, benzoic acid has no such electron-withdrawing substituent.
What is the chemical formula of aniline hydrochloride?
The chemical formula of aniline hydrochloride is C6H7N·HCl.

Ortho effect on acidity of carboxylic acid?
The ortho effect refers to the decrease in acidity of a carboxylic acid when bulky substituents are present at the ortho positions of the phenyl ring. This is due to the steric hindrance caused by the bulky groups, which makes it more difficult for the carboxylate anion to be stabilized, resulting in lower acidity.
Why direct halogenation of aniline is not possible?
Direct halogenation of aniline is not possible because aniline is a meta directing group. Due to the lone pair on the nitrogen atom, the halogenation reaction occurs at the meta position on the benzene ring instead of the ortho or para positions. This makes direct halogenation of aniline inefficient and typically requires additional functional group modifications to achieve halogenation at the desired 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 . . . . .

What brand of birth control pills have ortho tricyclen?
Ortho Tricyclen is made by Ortho.
Why does aniline when subjected to nitration conditions followed by a basic work up form the meta nitroanline and not ortho or para?
It reacts with the acidic conditions (since the NH2 is basic) to form the meta-directing electron withdrawing group NH3. This forms the meta-nitroaniline.
Where is Aniline found?
Aniline is a type of chemical found in cigarette smoke.
