Vedclass · Answer

(B) From the given structure,we can observe the valency of each element based on the number of bonds formed:$1$. Element $X$ forms $2$ single bonds and $1$ double bond,implying a total of $4$ bonds. This corresponds to a valency of $4$.$2$. Element $Y$ forms $2$ single bonds and $1$ double bond,implying a total of $4$ bonds. This corresponds to a valency of $4$.$3$. Element $Z$ forms $1$ single bond,implying a valency of $1$.Analyzing option $D$: If $X = P$,$Y = Si$,and $Z = H$,the structure corresponds to a derivative of a cyclic silane or similar compound,but let's re-evaluate based on standard valency. Actually,looking at the structure: $X$ is bonded to two $Y$ atoms (one double,one single),$Y$ is bonded to two $Z$ atoms and two $X$ atoms. If $X = N$,$Y = P$,$Z = Cl$,this matches the structure of phosphonitrilic chloride $(NPCl_2)_3$ where $N$ is $X$,$P$ is $Y$,and $Cl$ is $Z$. In $(NPCl_2)_3$,$N$ has a valency of $3$ (forming $2$ bonds in the ring and $1$ lone pair),and $P$ has a valency of $5$ (forming $4$ bonds in the ring and $2$ bonds to $Cl$). The provided diagram shows $X$ forming $3$ bonds and $Y$ forming $4$ bonds. Thus,$X=N$ (valency $3$),$Y=P$ (valency $5$),$Z=Cl$ (valency $1$) fits the chemical connectivity.

If the structure of a stable molecule containing atoms of elements $X, Y$,and $Z$ is as shown in the figure,what could the elements $X, Y$,and $Z$ be respectively?
