316294 Thiosulphate reacts differently with iodine and bromine in the reactions given below:
\({\mathrm{2 \mathrm{~S}_{2} \mathrm{O}_{3}^{2-}+\mathrm{I}_{2} \rightarrow \mathrm{S}_{4} \mathrm{O}_{6}^{2-}+2 \mathrm{I}^{-}}}\)
\({\mathrm{\mathrm{S}_{2} \mathrm{O}_{3}^{2-}+5 \mathrm{Br}_{2}+5 \mathrm{H}_{2} \mathrm{O} \rightarrow 2 \mathrm{SO}_{4}^{2-}+10 \mathrm{Br}^{-}+10 \mathrm{H}^{+}}}\)
Which of the following statement justifies the above dual behaviour of thiosulphate?

316295 Assertion :
\(\mathrm{F}_{2}\) has high reactivity.
Reason :
\({\rm{F}} - {\rm{F}}\) bond has low bond dissociation enthalpy.

316296 Assertion :
Trisilylamine is a relatively stronger base compared with trimethylamine.
Reason :
In trisilylamine, \(\mathrm{N}\) atom is \({\text{s}}{{\text{p}}^{\text{2}}}\) - hybridized and lone pair on \(\mathrm{N}\) is involved in back \(\pi\) bonding

316297 The reducing character of hydrides of group 14 elements is :

316298 Hydrides of germanium are called ____
