Consider the following order: (i) HF gt HCl gt HBr gt HI: Lewis basic

1.	Consider the following order: (i) HF gt HCl gt HBr gt HI: Lewis basic character (ii) CH_(4) lt C Cl_(4) lt CF_(4): Electronegatively of central 'C'- atom (iii) Mg^(2+) lt K^(+) lt S^(2-) lt Se^(2+) Stable oxidation state (vi) LiF gt NaF gt KF gt RbF, Lattice energy (vii) F^(-)(aq) gt Cl^(-)(aq) gt Br^(-) (aq) gt I^(-) (aq), Electrical conductance (viii) Li^(+) lt Mg^(2+) lt Al^(3+) : Hydration energy (ix) Cl gt Br gt F gt I: Electron affinity (x) BeCl_(2) lt AlCl_(3) lt SiCl_(4): Lewis acidic character Then calculate value of (x-y), where x and y are correct and incorrect order respectively.
Answer» Solution :(i), (II), (III),(v), (vi), (VII) & (ix) are true were as (iv), (vii) & (ix) are FALSE.
