an amine each with basic strength greater than and less than N-Methylmethanamine ingaseous state

To determine amines with basic strength greater than and less than N-Methylmethanamine in the gaseous state, we need to compare their basicity.

Step 1: Understand the concept of basicity in amines. Basicity refers to the ability of a compound to accept a proton (H+) and form a positively charged species. In general, the basicity of an amine depends on the availability of its lone pair of electrons.

Step 2: Compare the basicity of N-Methylmethanamine with other amines. N-Methylmethanamine has a methyl group attached to the nitrogen atom, which can donate electron density and decrease the basicity compared to primary amines. Therefore, we need to look for amines that have a higher basicity than N-Methylmethanamine.

Step 3: Consider the factors that affect basicity. The basicity of an amine can be influenced by the electron-donating or electron-withdrawing groups attached to the nitrogen atom. Electron-donating groups increase the basicity, while electron-withdrawing groups decrease it.

Step 4: Look for amines with electron-donating groups. Amines with alkyl groups (such as ethylamine or propylamine) have higher basicity than N-Methylmethanamine because the alkyl groups donate electron density to the nitrogen atom.

Step 5: Consider amines with aromatic rings. Amines with aromatic rings, such as aniline, have higher basicity than N-Methylmethanamine due to the resonance stabilization of the lone pair of electrons on the nitrogen atom.

Step 6: Compare the basicity of amines with electron-withdrawing groups. Amines with electron-withdrawing groups, such as nitro groups, have lower basicity than N-Methylmethanamine because these groups withdraw electron density from the nitrogen atom.

Step 7: Analyze the basicity trends. Based on the above comparisons, we can conclude that amines with alkyl groups or aromatic rings have higher basicity than N-Methylmethanamine, while amines with electron-withdrawing groups have lower basicity.

By following these steps, you can identify amines with basic strength greater than and less than N-Methylmethanamine in the gaseous state.
