Indicate the σ and π bonds in this molecule HCONHCH3

1. (σC-N) =4,  (σC-H) = 2,  (σN-H) = 1, and  (πC-O) = 1

2. (σC-N) =2,  (σC-H) = 4,  (σN-H) = 1, and  (πC-O) = 1

3. (σC-N) =1,  (σC-H) = 4,  (σN-H) = 2, and  (πC-O) = 1

4. (σC-N) =1,  (σC-H) = 4,  (σN-H) = 1, and i (πC-O) = 2

 
 
Hint: A single bond is a sigma bond while a multiple bonds is composed of one sigma bond together with pi or other bonds. A double bond has one sigma plus one pi bond, and a triple bond has one sigma plus two pi bonds

Explanation:

Step 1: Below is the structure of HCONHCH3

 
 
Step 2: Count the sigma, and Pi bond in the above mention compound structure
 
There are two C-N sigma (σC-N)  bonds, four C-H sigma (σC-H) bonds, one N_H sigma (σN-H) bonds, and one C=O pi (πC-O) bond in this  compound.
