[5] AIEEE 2011 Section : Chemistry AIEEE 2011 / Code C 31. In scene of the lanthanoids, which of the followers 36. statements is non correct? (1) Availability of 4f electrons results in the brass of compounds in +4 state for all the members of the series. (2) There is a gradual go down in the radii of the members with increasing atomic number in the series. (3) altogether the members exhibit +3 oxidisation state. (4) Because of similar properties the separation of autonomic nervous system: lanthanoids is not easy. autonomic nervous system: [1] 37. 32. In a manifestation centred cubelike lattice, atom A occupies the corner positions and atom B occupies the face centre positions. If whizz atom of B is absentminded from one of the face centred points, the formula of the compound is (1) A 2 B5 (3) AB2 autonomic nervous system: [1] 33. The magnetic moment (spin only) of NiCl 4 4? a and b atomic number 18 van der Waals constants for gases. centiliter is more easily liquefied than ethane because (1) a for Cl 2 ? a for C 2 H 6 but b for Cl 2 ? b for C 2 H 6 (2) a and b for Cl 2 ? a and b for C 2 H 6 (3) a and b for Cl 2 ? a and b for C 2 H 6 (4) a for Cl 2 ? a for C 2 H 6 but b for Cl2 ? b for C2 H 6 [2] ? ? The hybridisation of orbitals of N atom in NO 3 , NO 2 ? and NH 4 are respectively: (1) sp 2 , sp 3 , sp (3) sp 2 , sp, sp 3 (2) sp, sp 2 , sp 3 (4) sp, sp 3 , sp 2 (2) A 2 B (4) A 2 B3 Ans: [3] 38.
