Arrange them on the basis of electronegativity of elements increases H – InterviewSolution

1.	Arrange them on the basis of electronegativity of elements increases H2O , NH3 , HF , CH3 Book Solution CH3
Answer» Arrange them on the basis of electronegativity of elements increases H₂O , NH₃, HF , CH3 Book Solution CH3 My Problem Electronegativity of C is 2.5 so it is first. Electronegativity of N is 3.0 so it is second. But how I can differentiate between H2O and HF Is my way of solving this problem is correct and if not then what is correct way tell me.
