An Organic Compound Has The Formula CH3NO. How Many Valence Electrons Does This Molecule Have? Choose One:
A 10
B 16
C 18
D 22
The Correct Answer and Explanation is :
The correct answer is B. 16.
To calculate the number of valence electrons in an organic compound like CH3NO (methyl nitroxide), we need to count the valence electrons from each atom in the molecule. Here’s how we do that step by step:
- Carbon (C): Carbon is in Group 14 of the periodic table, so it has 4 valence electrons.
- Hydrogen (H): Hydrogen is in Group 1 of the periodic table, and each hydrogen atom has 1 valence electron. There are three hydrogens in the molecule, so we get 3 × 1 = 3 valence electrons from hydrogen.
- Nitrogen (N): Nitrogen is in Group 15 of the periodic table, so it has 5 valence electrons.
- Oxygen (O): Oxygen is in Group 16 of the periodic table, and it has 6 valence electrons.
Now, we add up the valence electrons from each atom:
- Carbon (C) contributes 4.
- Hydrogen (H) contributes 3 (from 3 hydrogens).
- Nitrogen (N) contributes 5.
- Oxygen (O) contributes 6.
Total valence electrons = 4 (C) + 3 (H) + 5 (N) + 6 (O) = 16 valence electrons.
Thus, the organic compound CH3NO has a total of 16 valence electrons.
Let me generate an image that shows the structure of CH3NO with the correct number of valence electrons.
Here’s the diagram showing the structure of CH3NO along with the distribution of valence electrons from each atom. This should help illustrate how the total number of valence electrons comes to 16. Let me know if you need any more details or further explanations!
