In group $-15$,as we move from $N$ to $Bi$,the $M_2O_3$ type oxides become ...... .

Which of the following elements of group $15$ $(VA)$ does not show allotropy?

When $NH_3$ is passed over heated $CuO$,it gets oxidized to form .................. .

The reaction of nitric oxide with ozone produces which gases?

Match the List-$I$ with List-$II$.

List-$I$ (Family)	List-$II$ (Symbol of Element)
$A$. Pnictogen (group $15$)	$I$. $Ts$
$B$. Chalcogen	$II$. $Og$
$C$. Halogen	$III$. $Lv$
$D$. Noble gas	$IV$. $Mc$

Choose the correct answer from the options given below:

Given below are two statements:
Statement-$I$: Element '$X$' and '$Y$' are the most and least electronegative elements, respectively, among $N, As, Sb$ and $P$. The nature of the oxides $X_{2}O_{3}$ and $Y_{2}O_{3}$ is acidic and amphoteric, respectively.
Statement-$II$: $BCl_{3}$ is covalent in nature and gets hydrolysed in water. It produces $[B(OH)_{4}]^{-}$ and $HCl$ in aqueous medium.
