(a) Among the hydrides of group 16, write the hydride
(i) Which is a strong reducing agent.
(ii) Which has maximum bond angle.
(iii) Which is most thermally stable.
Give suitable reason in each.
(b) Complete the following equations :
(a)
(i) H2Te is a strong reducing agent because of low bond dissociation enthalpy
(ii) H2O has maximum bond angle, because of small size and high electronegativity of oxygen, bond pair–bond pair repulsion is more.
(iii) H2O is most thermally stable, because of high bond dissociation enthalpy.
(b) S + 2H2SO4 3SO2 + 2H2O
Cl2 + NaOH NaCl + NaOCl + H2O
