1.	Explain the following: (a) Arrange HCI, HI, HBr, HF in increasing order of acidic strength. (b) Draw structure ofIF_(4)^(-)(c) Why are interhalogen compounds more reactive than related elemental halogens ? (d) Write chemical formula of Laughing gas. (e) Why molecular nitrogen is not so reactive ?
Answer» Solution :(a) The increasing order of ACIDIC STRENGTH is HF < HCI < HBr < HI (b) Structure of `IF_(4)^(-)` In `IF_(4)^(-)`, Iodine atom is in `sp^3d^2`hybridisation state. (c) Interhalogen compounds are more reactive than halogens because the bonds are more polar and weaker in interhalogens as compared to in halogens. (d) `N_2O` (e) This is because in N `-=` N, the BOND length is small and it has high bond energy (945 kJ /mol).
