Why CH3 2NH is more basic than CH3 3n in an aqueous solution?

In (CH3)3N, there is maximum steric hindrance and least solvation, but in (CH3)2NH, the solvation is more and the steric hindrance is less than in (CH3)3N. Although the +I effect is less because there are two methyl groups, di-methyl amine is still a stronger base than tri-methyl amine.

Which is most basic in aqueous solution CH3NH2 CH3 2NH CH3 3n c6h5nh2?

(CH₃)₂NH is most basic most basic among all others. Basicity is the ability of the atom to donate its lone pair of electrons.

Is CH3 2NH more basic than CH3NH2?

The correct order of increasing basic nature for the bases NH3, CH3NH2 and (CH3)2NH is. Except the amines containing tertiary butyl group, all lower aliphatic amines are stronger bases than ammonia because of +I (inductive) effect.

Which is more basic c6h5nh2 or CH3 2NH?

In C6H5CH2NH2, N is not directly attached to the benzene ring. Thus, its lone pair is not delocalized over the benzene ring. Therefore, the electrons on the N atom are more easily available for protonation in C6H5CH2NH2 than in C6H5NH2 i.e., C6H5CH2NH2 is more basic than C6H5NH2.

Which is more basic CH3 2nh and CH3 3N?

(CH3)2NH is more basic than (CH3)3N in an aqueous solution. The order of basic strength of aliphatic amines in the aqueous phase is based on the following factors: Steric factor: Alkyl group is larger than hydrogen atom that causes steric hindrance to attack of acid.

Does CH3 3N have a higher boiling point than CH3 2nh?

Among (CH3)3N and CH3NH2 , amine with methyl groups attached has the higher boiling point.

Which of the following compounds is are more basic than CH3NH2?

d : The increasing order of basicity of the given compounds is CH32NH > CH3NH2 > CH33N > C6H5NH2 Due to the +I effect of alkyl groups the electron density on nitrogen increases and thus the availability of the lone pair of electrons to proton increases and hence the basicity of amines also increases.

Which one of the following is the least basic CH3NH2?

The phenyl group is an electron-withdrawing group (-I) and the lone pair of nitrogen at amine group delocalizes within the phenyl ring which reduces the electron density and makes the substance least basic.

Why is CH3 2NH a base?

Dimethylamine ((CH3)2NH) is a weak base. In aqueous solution at 25°C, it reacts with water to produce its conjugate acid, the dimethylammonium ion ((CH3)2NH2+), and the hydroxide ion (OH-).

Which of the following is are the stronger base than CH3NH2 in aqueous solution?

In aqueous solution, trimethylamine is more basic than methylamine. In aqueous solution, trimethylamine is more basic than methylamine.

Which of the two is more basic c6h5nh2 or c6h5ch2nh2?

Thus, in C6H5NHCH3, the −R effect of −C6H5 group decreases the electron density over the N-atom. Therefore, C6H5CH2NH2 is more basic than C6H5NHCH3. Hence, the increasing order of the basic strengths of the given compounds is as follows: C6H5NH2 < C6H5NHCH3 < C6H5CH2NH2.

Which of the following is most basic c6h5nh2?

Aniline is the Least Basic.

Which is more basic (CH3)2NH or (Ch 3)3N in an aqueous solution?

Give reasons : (CH3)2NH is more basic than (CH3)3N in an aqueous solution. (CH 3) 2 NH is more basic than (CH 3) 3 N in an aqueous solution. Please log in or register to add a comment.

What is the difference between (CH3) 2 NH and (Ch 3) 3 N?

(i) (CH 3) 2 NH is more basic than (CH 3) 3 N in an aqueous solution. (ii) Aromatic diazonium salts are more stable than aliphatic diazonium salts.

Why is ch3o-ch=CH2 more stable than but-2-ene?

In the second compound, stability is attributed to hyperconjugation due to presence of alpha hydrogens. But by priority rule, stability rendered due to mesomeric effect (by conjugation) is more than that due to hyperconjugation. Thus, CH3O-CH=CH2 is more stable than but-2-ene.

What is the role of alkyl group in CH3NH2?

See, In CH3NH2 alkyl group is attached to nitrogen or NH2 group which will increase the electron density on nitrogen due to its +I effect ( electron donating nature of alkyl group ) .
