1.	Explain why the dipole moment values of hydrogen halides decrease from H-F to H-I.
Answer» Solution :Electronegativity of halogens decrese I the order `F GT CL gt Br lt I`. In hydrogen halides, as the difference in electronegativity between H and X (X=halogen) decreses, the bond POLARITY decreses. Hence the H-X bond dipole moment decreses from HF to HI.
