Answer» (a) (i) See Q. 29 (b) (ii), Delhi Board, 2010. (ii) Because of small size, highest eledtro negativity and low bond dissociation enthalp) of f-f bond, fluorine is most reactive. (b) (i) `C+2H_2SO_4("conc".)to2SO_2+CO_2+2H_2O` (ii) `P_4+3NaOH+3H_2Otounderset("Phosphine")(PH_3)+underset("Sodium hypaphosphite")(3NaH_2PO_2)` (iii) `{:(C_2+3F_2overset("heat")to2ClF_3),(""" (excess)"):}` |
