Select the correct statement for the following molecules.

(P) ${\mathrm{PF}}_2{\left({\mathrm{CH}}_3\right)}_3$    (Q) ${\mathrm{PF}}_2{\left({\mathrm{CF}}_3\right)}_3$

The structure,

$\mathrm{x}>\mathrm{y}$ because $-{\mathrm{CF}}_3$ has greater $-\mathrm{I}$ than $-{\mathrm{CH}}_3$ group.
So, e correct statement for the ${\mathrm{PF}}_2{\left({\mathrm{CH}}_3\right)}_3$ and ${\mathrm{PF}}_2{\left({\mathrm{CF}}_3\right)}_3$ molecules are,

a) Both have trigonal bipyramidal structure .

b) Both have same dipole moment.
c) P-F bond length is longer in ${\mathrm{PF}}_2({\mathrm{CH}}_3{)}_3$ than the ${\mathrm{PF}}_2({\mathrm{CF}}_3{)}_3$.

Hence, the correct option is a,b,c.
