hydrocarbon is ethene which is used to test for saturation and it undergoes addition reaction
When acids react with water, H ions are released which then combine with water molecules to form H₃O⁺
Explanation:
Since, the atomic number of nitrogen is 7 and its electronic distribution is 2, 5. So, in order to attain stability it needs to gain 3 electrons.
Hence, when it chemically combines another nitrogen atom then as both the atoms are non-metals. So, sharing of electrons will take place.
Also, there is no difference in electronegativity of two nitrogen atoms. Hence, compound formed
is non-polar covalent in nature.
The last set which is n=4 l=3 m=3 is a valid set
