Sulphur has greater tendency for catenation than oxygen. Explain.

State reasons for each of the following : (i) All the P-Cl bonds in PCl_5 molecule are not equivalent. (ii) Sulphur has greater tendency for catenation than oxygen.

Why does sulphur have greater tendency for catenation than oxygen ?

Account for the following : (i) NH_(3) is a stronger base than PH_(3) (ii) Sulphur has a greater tendency for catention than oxygen. (iii) Bond dissociation energy of F_(2) is less than that of Cl_(2) . (OR) Explain the following situations : (i) In the structure of HNO_(3) moleucle, the N-O bond (121 pm) is shorter than the N-OH bond (140 pm). (ii) SF_(4) is easily hydrolysed whereas SF_(6) is not easily hydrolysed. (iii) XeF_(2) has a straight linear structure and not a bent angular structure.

Draw the structures of the following : (i) XeF_(4) (ii) H_(2)S_(2)O_(7) (iii) Structure of SO_(3)^(2-) Exaplain the following observations : (b) Examplain the following observations : (i) Phosphours has a greater tendency for catenation than nitrogen. (ii) The negative value of electron gain enthalpy is less for fluorine than that for chlorine. (iii) Hydrogen fluoride has a much higher boiling point than hydrogen chloride.
