1.	Consider the following statements and arrange in the order of true /false as given in the codes. S_1:In I Cl_2^(-), CIF_3 and TeCl_4 the number of lone pairs of electrons on central atoms are 3,2 and 1 respectively. S_2:Amongest NO, C_2, O_2^(-) , He_2^+, the increasing order of bond dissociation energies of He_2^+ lt O_2^(-) lt C_2 lt NO. S_3:Amongst CO, CO_2, CO_3^(2-),CH_3OH, the correct order from the weakest to the strongest carbon - oxygen bond is CH_3OH lt CO_3^(2-) lt CO_2 lt CO S_4:The hybridisation of boron in Cl_2BBCl_2 is the same which nitrogen has in CINO molecules.
