Which one of the following pairs is paraagnetic 2) P,0,. N,0, 3) CIO, NO, 4) So, NO 1) CLO, SO, 2. co. NO; BO The correct increasing order of extent of p-bonding in above molecules are 4) II< II <1 I)I<II < I 2) III < II<I 3y II <I<I 3. Which of the following comparison of bond length (C-0) is incorrect for the bonds indicated the given molecule ? 2) I1< I1 4) III = IV 1)1-11 3) IV <1 Bond angle in the following conversions decreases except when 2) NH, into N, 4. 3) So, into SO, 4) CO, into CO, 1) NH, into NH, In the compounás of the type ECI, where E- B, P, As (or) Bi the angles Cl-E- CI for differn elements E are in the order 1) B>P=As = Bi 6. Statement-1: Bond angle in N'H, is more than that in NH, Statermient-2 : No lone pair bond pair repulsion is present inN'H, 1) Statement-1 is True, Statement-2 is True; Statement-2 is a Correct explanation for Statement- 2) Statement-l is True, Statement-2 is True: Statement-2 is NOT a Correct explanation for Statement- 3) Statement-1 is True, Statement-2 is False 3. 2) B>P> Ai > Bi 3) B<P-As Bi 4) B<P<As < Bi 4) Statement-1 is False, Statement-2 is True T. Statement-l: Trisilyl amine is stronger bose than trimethyl amine Sutement-2 In trisilyl amine a pr-dn back bonding exists which leads to docrease in the electron density on nitrogen atom. a In which of the following moleculesions are all the bonds not equal ? 1) XeF, The comect order of the thermal stability of hydrogen halides (H- X) is ) HI>HCI <HF>HBr 3) HE> HCI > FIBr HI 2) BE, 3) SF, 4) SiF. 2) HCI < HF > HBr < HI 4) HI > HBr> HCI > HF Which one of the following pairs is paraagnetic 2) P,0,.
