The α-carbon atom bonded to the nitrogen of an alkylamine usually appears in what chemical shift (δ) range?

A) 5-20
B) 30-50
C) 80-100
D) 120-150
E) 180-220

Alkylamine

A compound resulting from the replacement of one or more hydrogen atoms of ammonia (NH3) with alkyl groups.

α-Carbon

The first carbon atom attached directly to a functional group in an organic molecule.

Chemical Shift

A term used in nuclear magnetic resonance (NMR) spectroscopy to describe the change in the resonance frequency of a nucleus due to its chemical environment.

  • Employ infrared (IR), nuclear magnetic resonance (NMR), and mass spectroscopic techniques to differentiate and identify various amines.

Final Answer :
B
Explanation :
The α-carbon atom bonded to the nitrogen of an alkylamine typically appears in the chemical shift range of 30-50 δ in NMR spectroscopy due to the electron-donating effect of the nitrogen, which slightly deshields the carbon atom.
