Step 1: Methylamine as a Base
Methylamine (CH\(_3\)NH\(_2\)) is a stronger base than ammonia (NH\(_3\)) because the methyl group (CH\(_3\)) is an electron-donating group, which increases the electron density on nitrogen and makes it more readily available to accept protons.
Step 2: Explanation of Other Options
Option (b) is incorrect because methylamine is a stronger base than ammonia.
Option (c) is incorrect because methylamine is not acidic, it is basic.
Option (d) is incorrect because both methylamine and ammonia can form salts with acids, but this does not affect their basicity directly.
Step 3: Conclusion
Thus, methylamine is a stronger base than NH\(_3\).
