Which of the following amines is the weakest base?

Benzenamine is the weakest base among the following since the delocalisation of the lone pair of electrons in it is not possible due to which the electron density on the molecule is fairly low and the compound acts as the weak base in the presence of the acid.

Which amine is the weaker base and which is a stronger base?

Comparing the other two to ammonia, you will see that methylamine is a stronger base, whereas phenylamine is very much weaker. Methylamine is typical of aliphatic primary amines – where the -NH2 group is attached to a carbon chain. All aliphatic primary amines are stronger bases than ammonia.

Which one of the following is the weakest Lewis base?

The weakest Lewis base is Cl-, because it has octet rule. Cl – won’t donate electrons easily.

Is znoh2 a weak base?

Zn(OH)2 is a weak base. Among the given hydroxides, Zn(OH)2 is the weakest base.

Which amine is the strongest base?

Amine Answers The amide ion is the strongest base since it has two pairs of non-bonding electrons (more electron-electron repulsion) compared to ammonia which only has one. Ammonium is not basic since it has no lone pair to donate as a base. Amines are stronger bases than alcohols.

Is an amine a weak base?

Amines, unless they have four R- groups attached (a quaternary amine) have a lone pair of electrons, which just like the lone pair in ammonia, can accept a proton. Hence amines, like ammonia, are weak bases.

Which of the following is weak base *?

Ammonia is a weak base.

Which is the weaker base than aniline?

As a result, the availability of the unshared pair of electrons on nitrogen atom in p – nitroaniline is highly reduced as compared to the unshared electron pair on nitrogen in aniline. For this reason, p – nitroaniline behaces as a weaker base compared to anline.

Why aniline is weaker base than amine?

In the case of aromatic amine, the lone pair undergoes conjugation with the benzene. As a result, lone pair availability decreases as well as the basicity. In case of aniline due to conjugation the lone pair density is less than that of methylamine. Due to this reason, aniline is less basic than methylamine.

Why aniline is weaker base than cyclohexyl amine?

Aniline and cyclohexylamine both hane NH2 group and six carbon ring but the difference in basicity lies in a manner that aniline is a weak base then cyclohexylamine because aniline is an aromatic ring, because of the electron-withdrawing effect of the phenyl group aniline is a weak base.
