${\lambda _{NaCl}} = 38.2\;oh{m^{ - 1}}\,c{m^2}\,gme{q^{ - 1}}$,
${\lambda _{HCl}} = 203\;oh{m^{ - 1}}\,c{m^2}\,gme{q^{ - 1}}$,
What is the value of ${\lambda _{ClC{H_2}COOH}}$ .............. ${\rm{Oh}}{{\rm{m}}^{ - 1}}{\mkern 1mu} {\rm{c}}{{\rm{m}}^2}{\rm{gm}}\,{\rm{e}}{{\rm{q}}^{ - 1}}$
$A$. All group $16$ elements form oxides of general formula $\mathrm{EO}_2$ and $\mathrm{EO}_3$ where $\mathrm{E}=\mathrm{S}, \mathrm{Se}, \mathrm{Te}$ and Po. Both the types of oxides are acidic in nature.
$B$. $\mathrm{TeO}_2$ is an oxidising agent while $\mathrm{SO}_2$ is reducing in nature.
$C$. The reducing property decreases from $\mathrm{H}_2 \mathrm{~S}$ to $\mathrm{H}_2 \mathrm{Te}$ down the group.
$D$. The ozone molecule contains five lone pairs of electrons.
