Question

In the following compounds, the decreasing order of basic strength will be ______.

विकल्प

• \[\ce{C2H5NH2 > NH3 > (C2H5)2NH}\]

• \[\ce{(C2H5)2NH > NH3 > C2H5NH2}\]

• \[\ce{(C2H5)2NH > C2H5NH2 > NH3}\]

• \[\ce{NH3 > C2H5NH2 > (C2H5)2NH}\]

Answer 1

In the following compounds, the decreasing order of basic strength will be \[\underline{\ce{(C2H5)2NH > C2H5NH2 > NH3}}\].

Explanation:

Basic strength in aqueous solution \[\ce{(C2H5)2NH > C2H5NH2 > NH3}\].

Considering +I effect and stability of conjugate acid in aqueous medium due to hydrogen bonding.
