Why does hydrogen bond so tightly to oxygen during cellular respiration? (1 point)
It is less electronegative than oxygen
O It is electronegative, but oxygen is not.
© It is more electronegative than oxygen.
It is not electronegative, but oxygen is.
The correct answer is: © It is more electronegative than oxygen.
Hydrogen bonds are formed between the hydrogen atom of one molecule and the oxygen atom of another molecule. Hydrogen is less electronegative than oxygen, meaning it has a lower affinity for electrons. Oxygen, on the other hand, is more electronegative, meaning it has a higher affinity for electrons. The difference in electronegativity between hydrogen and oxygen allows for a strong attraction between the two atoms and the formation of a tight hydrogen bond.
