(CH3)2NH is a secondary amine known as dimethyl amine. Aliphatic amines can be regarded as substituted ammonia. When one hydrogen in the ammonia, NH3 molecule is substituted with an alkyl group (eg. –CH3 group) it is said to be a primary amine.

Keeping this in view, why ch3 2nh is more basic than ch3 3n?
(CH3)3N is less basic than (CH3)2NH because (CH3)2NH is not sterically hindered like (CH3)3N. Secondly (CH3)2NH can form Hydrogen bonds with water more extensively.
which is more basic among these and why ch3nh2 and ch3 2nh? (ii) C6H5N(CH3)2 is more basic than C6H5NH2 due to the presence of the +I effect of two −CH3 groups in C6H5N(CH3)2. Further, CH3NH2 contains one −CH3 group while (C2H5)2NH contains two −C2H5 groups. Thus, (C2H5)2 NH is more basic than C2H5NH2.
Correspondingly, is ch3 2nh soluble in water?
Contact with the unconfined liquid can cause frostbite by evaporative cooling and chemical type burns. Density of liquid 5.5 lb / gal. The gas, which is corrosive, dissolves readily in water to form flammable corrosive solutions.
Is NH ch3 2 a weak base?

Which is most basic in aqua solution?
∴CH3COOK is the most basic in aqueous solution since it form from strong base KOH and weak acid CH3COOH.
Which is the most basic in aqueous solution?
KOH is the strongest base than Fe(OH)3, Pb(OH)2, Al(OH)3. Hence, it is the most basic among all.
Is N ch3 3 a strong base?
Trimethylamine, N(CH3)3, is the molecule that is responsible for the “fishy smell” of seafood. It has a Kb of 6.3 x 10 -5, making it a moderately-strong weak base.
Which is a stronger base nh3 or ch3nh2?
In general, methylamine (CH3NH2) is a stronger base than ammonia (NH3) and dimethylamine ((CH3)2NH) is a stronger. However, in water, triethylamine ((CH3CH2)3N) which should be even stronger based on stronger inductive effect, is a weaker base than dimethylamine or methylamine.
Is nh2 an acid or base?
The conjugate acid of NH2- is NH3, called ammonia. Ammonia is actually itself a weak base, so its conjugate base NH2- is an incredibly strong base so it can get an extra proton to regenerate NH3 which is much more stable.
Is NaCl an acid or base?
NaCl is formed by the reaction of HCl and NaOH. Both are strong acids and bases. When a strong acid and a strong base react together the resultant is salt and water. Therefore NaCl is a salt.
Is ch3 2nh an acid or base?
The quick answer is that (CH3)2NH is a base. That is how it behaves in water (i.e. Arrhenius definition). If you use the Bronsted-Lowry definition and are willing to use organic solvents, it”s a bit trickier. (CH3)2NH has a conjugate acid (CH3)2NH2+, making it a Bronsted-Lowry base.

What is the pH of 0.070 M dimethylamine? The K_b for dimethylamine is 5.9 x 10^-4.
Is dimethylamine water soluble?
Dimethylamine is a colourless flammable gas at room temperature. It has a pungent, fishy, or ammonia-like odour at room temperature and is shipped and marketed in compressed liquid form. It is very soluble in water and soluble in alcohol and ether.
Is ch3ch2 2nh an acid or base?
Examples of weak bases include ammonia, NH3, and diethylamine, (CH3CH2)2NH. Most weak bases are anions of weak acids. Weak bases do not furnish OH- ions by dissociation. Instead, they react with water to generate OH- ions.

Which is the strongest base?
The methyl anion H3C– was the strongest known base for 30 years, until Tian and colleagues made the lithium monoxide anion in 2008, which has held the record since. Now, scientists in Australia have knocked LiO– down to second place, making a gas-phase dianion with the highest basicity ever found.
