$PH_5, NCl_5$ and $OF_6$ do not exist

Vedclass · Answer

(A) $1$. $PH_5, NCl_5$ and $OF_6$ do not exist because $P$ cannot expand its octet to $5$ bonds due to steric hindrance,$N$ lacks $d$-orbitals to form $5$ bonds,and $O$ cannot form $6$ bonds due to its small size and lack of $d$-orbitals. Thus,this statement is true.$2$. $I_3^{-}$ has a linear geometry ($sp^3d$ hybridization with $3$ lone pairs on the central $I$ atom). Thus,this statement is false.$3$. $XeF_4$ has a square planar geometry,which is symmetric,making it non-polar. Thus,this statement is false.$4$. The bond order of $O_2$ is $2.0$ and the bond order of $O_2^{2-}$ (peroxide ion) is $1.0$. Thus,this statement is false.

Molecule	Hybridization	Geometry
$I$. $BrF_5$	$sp^3d^2$	Square pyramidal
$II$. $XeF_6$	$sp^3d^3$	Distorted octahedral
$III$. $SF_4$	$dsp^2$	Square planar
$IV$. $PbCl_2$	$sp$	Linear

$(I)$	Dipole moment	$NF_3 > NH_3 > BF_3$
$(II)$	Covalent bond length	$C-O > N-O > O-H$
$(III)$	Bond order	$C_2 > B_2 > He_2$
