Question

Another amino acid is alanine, which has the Lewis structure shown here. Predict the electron-pair geometry and local structure of the nitrogen atom, the three carbon atoms, and the oxygen atom with hydrogen attached:

CH3
H-N-C
-С—о—н
H H
:o:
:0=U
Transcribed Image Text:CH3 H-N-C -С—о—н H H :o: :0=U
Expert Solution
Step 1

Interpretation:

Electron pair geometry and local structure of the nitrogen atom, the three carbon atoms, and the oxygen atom with hydrogen to be predicted.

In organic compound, hybridization depends upon the number of sigma bonds and lone pair.

sp3 hybridization - Tetrahedral geometry:

4 sigma bonds

3 sigma bonds + 1 lone pair

2 sigma bonds + 2 lone pair

sp2 hybridization - trigonal planar geometry

3 sigma bonds

2 sigma bonds + 1 lone pair

sp hybridization - linear geometry

2 sigma bonds
