The correct onder of the lattice energies of the following inme compounds i 1) NaCI > MgBr, > CaO > ALO, 3) MEBI, > ALO,> Cao > 2) ALO, MgBr, > Ca0 NaC 4) ALO, > Cao MyBr, NaCI In which of the folowing the hvdration enery highet itan the latiicr energ NaCI 2. 1) MgSO, 2) RaSO, 3) SrSO, 4) BASO, A molecule which cannot exist theoreticilly is 1) SF 2) OF, 4) 0,F 4. Among LiCI, BeC. BCI, and CC, the covalent bond churactir follows the order 2) LICI < BeCl, < BCI, < CCI, 4) LICI BeCI, < BCI, CCI, 3) OF 1) LICI > BeCl, > BCI, > CCI, 3) LICI > BeCl, > CCI,> BCI, 5. Thie correct order of decrensing polarisability of kon is )CI > Br> >F 2) F>> Br> CI 3)1> Br > CI >F 4) F> CI> Br> 6, Which ion has a higher polarising power ? 1) Mg 2) AP 3) Ca 4) Na 7. The correct order of increasing covalent cluracier is 1) NaCI < LICI < BeCl. 2) BeCl, < NaCI < LICI 4) LICI < NaCI < BeCI, 3) BeCl, < LiCI < NaCI The puir with more ionic nture and less mn.pl respectively among lithun halides L) LiF, Lil 3) LIBr, Lif 4) LiF. LICT 2) LICI, LIF * One would expect proton to have very large I) ionisation potential 3) charge 4) bydration energy 2) radius 10. Octer nulo is not valid for the molecule 1) CO, 11. Hypervalent vompound is 3) 0, 4) PCI, 2) NO 3) Bef, 4) CH, 1) IF, 2) NH, 12. Which formulae does not correctly repronents the bending capacity of the atom involved 3) 0N0 4) H-Cc H-P
