What are the derivatives of aniline?
Amines, Aromatic, Methylenedianiline.
What is the PKA of aniline?
Acidity (pKa) 4.63 (conjugate acid; H2O)
Which of the following aniline derivatives is most basic?
Solution : para substituted anilines are more basic than ortho substituted aniline because of para effect.
Which drug is Alaninamide derivative?

Which aniline are highly acidic?
Anilinium ion is most acidic as on deprotonation, it will give aniline in which lone pair on nitrogen is in resonance with benzene ring.
Why aniline is aromatic?
Because aniline has an amino group in its structure, it is also an amine, hence it is classified as an aromatic amine.
Is paracetamol an aniline derivative?
Non-opioid analgesics are derived from three types of compounds: aniline derivatives, such as paracetamol; aspirin and other acidic NSAIDs; and non-acidic pyrazole drugs such as phenylbutazone and dipyrone. Paracetamol works at the supraspinal level by an as yet unknown mechanism.
What drug is used for congestive heart failure?
More aggressive diuretic therapy eg Loop diuretics such as Furosemide (Lasix), one of the most commonly used drugs in the treatment edema caused by congestive heart failure (CHF).
Which of the following is correct Iupac name of procainamide?
4-amino-N-2-(diethylamino)ethyl-benzamide (also known as para-amino-N-2-(diethylamino)ethyl-benzamide because the amino substituent is attached to the para-position, Arene substitution patterns of the benzene ring) is a synthetic organic compound with the chemical formula C13-H21-N3-O.
What is ortho effect in aniline?
The Ortho effect is specific to aniline and benzoic acids. It states that the ortho-substituted benzoic acids and anilines are respectively more acidic than benzoic acid and aniline. They can also greatly affect acidity through sterics, causing the group of carboxylic acids to bend out of the benzene ring plane.
What is the conjugate acid of aniline?
Table of bases and their conjugate acids
| Base | Conjugate acid |
|---|---|
| NH 3 Ammonia | NH + 4 Ammonium ion |
| C 5H 5N Pyridine | C 5H 6N + Pyridinium |
| C 6H 5NH 2 Aniline | C 6H 5NH + 3 Phenylammonium ion |
| C 6H 5CO − 2 Benzoate ion | C 6H 6CO 2 Benzoic acid |
What is the kb value of aniline?
Aniline (C6H5NH2, Kb = 4.3 times 10-10) is a weak base used in the manufacture of dyes.
Which 5 classes of drugs are used in the management of heart failure?
Five types of drugs were considered as the agents of choice in the treatment of chronic heart failure: angiotensin-converting enzyme (ACE) inhibitors, β-adrenoceptor antagonists (blockers), potassium sparing diuretic (spironolactone), cardiac glycosides, and diuretics other than the potassium-sparing class.
What classification is procainamide?
Procainamide is a medication used to manage and treat ventricular arrhythmias, supraventricular arrhythmias, atrial flutter, atrial fibrillation, AV nodal re-entrant tachycardia, and Wolf-Parkinson-White syndrome. It is a Class 1A antiarrhythmic agent.
Related aniline derivatives. Many analogues of aniline are known where the phenyl group is further substituted. These include toluidines, xylidines, chloroanilines, aminobenzoic acids, nitroanilines, and many others. They often are prepared by nitration of the substituted aromatic compounds followed by reduction.
What is the product formed when Aniline reacts with acid?
Aniline reacts with strong acids to form the anilinium (or phenylammonium) ion (C 6 H 5 -NH 3+ ).
What is the importance of aniline in pharmacology?
A well known analgesic drug named paracetamol is prepared from aniline. O-toluidine is a dye which is used in forensic science to take presumptive blood. The importance of aniline and its derivatives in various aspects has been studied by many researchers.
What is the reactivity of aniline derivatives of phenols?
Like phenols, aniline derivatives are highly susceptible to electrophilic substitution reactions. Its high reactivity reflects that it is an enamine, which enhances the electron-donating ability of the ring. For example, reaction of aniline with sulfuric acid at 180 °C produces sulfanilic acid, H 2NC 6H 4SO 3H.
