Why the litmus aniline is neutral?
Litmus is a weak acid that is primarily present in the form of its conjugate base at neutral pH, leading to its neutral color. Aniline, being a weak base, does not significantly affect the pH of the litmus solution, allowing it to remain neutral.
What color will aniline turn litmus paper?
Aneline is basic,so litmus color is changed into blue
Which is strong base aniline or o-nitroaniline?
Aniline is a stronger base than o-nitroaniline because the nitro group in o-nitroaniline is electron-withdrawing and decreases its basicity compared to aniline. In basicity trends for amines and anilines, the presence of electron-withdrawing groups decreases basicity.
Why aniline dissolve in acid hydrochloric solution?
In acid, the nitrogen gets protonated making the chloride (if using hydrochloric acid) salt of aniline, which is soluble. In a basic solution, the nitrogen is not protonated, so the solubility is much lower.
What are example of weak base?
Examples of weak bases include ammonia (NH3), methylamine (CH3NH2), and aniline (C6H5NH2). These compounds do not completely dissociate in water to release hydroxide ions but can still react with acids to form salts and water.
How do you write the nucleophilic substitution reactions for aniline and toluene?
aniline would go through an electrophilic substitution, it is a weak base

Aniline plus water plus FeCl3?
When aniline (C6H5NH2) is mixed with water and ferric chloride (FeCl3), a complex reaction occurs. Aniline, being a weak base, can form a soluble anilinium ion in the presence of water. The FeCl3 can react with the aniline to form a colored complex, often resulting in a deep violet or purple solution, which is indicative of the formation of a complex between the aniline and ferric ions. This reaction is often utilized in analytical chemistry to detect aniline and related compounds.

Is C6H7N strong base?
No, all isomers of this formula are neutral alcohols not the base.
Why aniline is weaker base than methylamine?
Since tha pka of the aniline ion is equal to 4.6, the anilinium ion is a stronger acid than the methylaminium ion, and aniline (c6h5nh2) is a weaker base than methylamine (ch3nh2).
Schiff base of aniline and benzaldehyde?
The Schiff base formed from aniline and benzaldehyde is N-phenylideneaniline. This compound is a imine derivative and is commonly used in organic synthesis reactions. It is formed by the condensation of aniline and benzaldehyde in the presence of a suitable catalyst.
What is balance equation for aniline with phenolphthalein indicator?
The balance equation for the reaction of aniline (C6H5NH2) with phenolphthalein as an indicator is not a simple chemical reaction but rather an acid-base equilibrium. Aniline acts as a weak base and can accept a proton (H+) to form its conjugate acid, C6H5NH3+. In a solution with phenolphthalein, which changes color in response to pH, the balance can be represented as: C6H5NH2 + H2O ⇌ C6H5NH3+ + OH- In this equilibrium, the presence of phenolphthalein indicates the pH level, changing color in acidic or basic conditions.
Why cyclohexylamine is a stronger base than aniline?
Cyclohexylamine is a stronger base than aniline because the nitrogen atom in cyclohexylamine is less hindered by bulky substituents than in aniline. This allows for easier access of the lone pair of electrons on nitrogen in cyclohexylamine, making it more available for proton transfer. Aniline's lone pair is more delocalized into the benzene ring, which reduces its basicity.
