Question

Which is more basic in methyl amine, dimethyl amine, trimethyl amine, benzene amine?

Answer 1

Answer:

trimethyl amine>dimethyl amine>methyl amine>benzene amine

Explanation:

we describe base as Lewis base here so compound which loses lone pair easily is the best base.

benzene amine lone pair is in conjunction so it's the worst.

remaining be explained by +m order

Answer 2

Answer:

Benzene amine is most basic of all followed by trimethyl amine, then dimethyl amine and methylamine in non-aqueous medium.

Since basicity of a amine depends upon ease of formation of cation, the above order is followed.

In aqueous medium the order is reversed since the greater the number of -H the more stable the compound will be and hence the more basic.
