Question

How many valence electrons needed To build molecular framework of

(CH3CH2CH2)2NH?

Answer 1

7/2 NH

amide linkage

3 valence

Answer 2

The valence electron is 3

Explanation:

• Amide-linkage (N-acylation) characterizes a stable amide-bond between the COOH-group of the fatty acid and α-NH2–group, usually a glycine residue at the N-terminus of proteins.

• The carbonyl carbon-to-nitrogen bond is called an amide linkage. This bond is quite stable and is found in the repeating units of protein molecules, where it is called a peptide linkage. Simple amides are named as derivatives of carboxylic acids

• the linkage is NH/2
