Which of the following statement is $INCORRECT$ ?
The direct reaction of xenon with fluorine leads to a series of compounds with oxidation numbers $+2,+4$ and $+6$ . XeF $4$ reacts violently with water to give $\mathrm{XeO}_3$. The compounds of xenon exhibit rich stereochemistry and their geometries can be deduced considering the total number of electron pairs in the valence shell.
$1.$ Argon is used in arc welding because of its
$(A)$ low reactivity with metal
$(B)$ ability to lower the melting point of metal
$(C)$ flammability
$(D)$ high calorific value
$2.$ The structure of $\mathrm{XeO}_3$ is
$(A)$ linear $(B)$ planar $(C)$ pyramidal $(D)$ $T$-shaped
$3.$ $\mathrm{XeF}_4$ and $\mathrm{XeF}_6$ are expected to be
$(A)$ oxidizing $(B)$ reducing $(C)$ unreactive $(D)$ strongly basic
Give the answer question $1,2$ and $3.$
$PH _{3}, B _{2} H _{6}, CCl _{4}, NH _{3}, LiH$ and $BCl _{3}$ is ..... .
$Mn{O_2}(s)\, + \,4{H^ + }(aq)\, + \,2{e^ - }\, \to \, M{n^{ + 2}}(aq)\, + \,2{H_2}O(l)\,;$ $E_2^o\, = \,1.21\,\,V$
$MnO_4^{ - 1}(aq)\, + \,4{H^ + }(aq)\, + \,3{e^ - }\, \to \, Mn{O_2}(s)\, + \,3{H_2}O(l)\,;$ $E_3^o\,?$
value of $E_3^o$ will be ............ $\mathrm{V}$
