Below is an incomplete Lewis structure for glycine. i. How many lone pairs of electrons are present on N-atom in the structure?

Question

Below is an incomplete Lewis structure for glycine. Complete the following Lewis structure and answer the following questions.

(Hint : Add lone pairs and multiple bonds to the structure below to give each atom a formal charge of zero.)

i. How many lone pairs of electrons are present on N-atom in the structure?

ii. How many pi bonds are present in the structure?

iii. How many sigma bonds are present in the structure?

Answer 1

The correct Lewis structure is :

i. The number of lone pairs of electrons on N-atom is 1.

ii. The number of pi bonds in the structure is 1.

iii. The number of sigma bonds in the structure is 9.
