Vedclass · Answer

(D) The ground state electronic configuration of $Cl$ $(Z=17)$ is $[Ne] 3s^2 3p_x^2 3p_y^2 3p_z^1$.In the first excited state,one electron from $3p$ moves to $3d$,giving $3$ unpaired electrons.In the second excited state,one electron from $3s$ moves to $3d$,giving $5$ unpaired electrons.In the third excited state,one more electron from $3p$ moves to $3d$,resulting in $7$ unpaired electrons $(3s^1, 3p_x^1, 3p_y^1, 3p_z^1, 3d^3)$.These $7$ unpaired electrons react with $7$ fluorine atoms to form $ClF_7$.The hybridization is $sp^3d^3$,which corresponds to a pentagonal bipyramidal geometry.

Chlorine atom,in its third excited state,reacts with fluorine to form a compound $X$. The formula and shape of $X$ are :
