Which of the following amines is the most basic? (2023) 2023
Step 1: Understand what amines are. Amines are compounds that contain a nitrogen atom bonded to hydrogen atoms or carbon groups.
Step 2: Know that basicity in amines refers to how well they can accept protons (H+ ions). The more basic an amine is, the more readily it can accept a proton.
Step 3: Identify the structure of dimethylamine. Dimethylamine has two methyl groups (CH3) attached to the nitrogen atom.
Step 4: Recognize the electron-donating effect of the methyl groups. Methyl groups can donate electron density to the nitrogen atom, making its lone pair of electrons more available to bond with protons.
Step 5: Compare dimethylamine with other amines. Other amines may have fewer or no electron-donating groups, making them less basic than dimethylamine.
Step 6: Conclude that dimethylamine is the most basic amine because the two methyl groups enhance the nitrogen's ability to accept protons.
