The hybridization of nitrogen in diethyl amine is
The hybridization of nitrogen in diethyl amine is
Sp2
Sp3d
Sp
Sp3
The Correct Option is D
Solution and Explanation
To determine the hybridization of nitrogen in diethyl amine (C4H11N), we first examine the structure of the molecule. Diethyl amine has the formula CH3CH2NHCH2CH3. In this molecule, the nitrogen atom forms three sigma bonds: two with carbon atoms and one with a hydrogen atom.
Hybridization is determined by the number of sigma bonds and lone pairs around the atom. The nitrogen in diethyl amine has:
- 3 sigma bonds (2 with carbon and 1 with hydrogen).
- 1 lone pair of electrons.
The total is 4, indicating sp3 hybridization. This is because:
- 1 s orbital and 3 p orbitals combine to form 4 equivalent sp3 hybrid orbitals.
Therefore, the hybridization of nitrogen in diethyl amine is sp3.

Amines are usually formed from amides, imides, halides, nitro compounds, etc. They exhibit hydrogen bonding which influences their physical properties. In alkyl amines, a combination of electron releasing, steric and H-bonding factors influence the stability of the substituted ammonium cations in protic polar solvents and thus affect the basic nature of amines. Alkyl amines are found to be stronger bases than ammonia. Amines being basic in nature, react with acids to form salts. Aryldiazonium salts, undergo replacement of the diazonium group with a variety of nucleophiles to produce aryl halides, cyanides, phenols and arenes.

Concepts Used:
Amines
Amine is a type of compound which is derived from ammonia (NH3). According to Organic chemistry, they are basically classified as the functional groups of the organic nitrogen compounds that contain nitrogen atoms with a lone pair.
Amine - Types
Primary Amines:
It is formed when one hydrogen atom in ammonia is substituted by an alkyl or aromatic group. Amino acids and methyl amine are the best examples that why aromatic amines include aniline.
Secondary Amines:
Amines that have two organic substitutes either alkyl or aryl ones or both and are bound to the nitrogen together with one hydrogen are termed as secondary amines. For Example, Dimethylamine.
Tertiary Amines:
Tertiary Amines are the amines where the nitrogen consists of three organic substitutes. For example, Trimethylamine and EDTA.
