JEE MAIN - Chemistry (2012 - No. 19)
In which of the following pairs the two species are not isostructural ?
$$CO_3^{2-}$$ and $$NO_3^-$$
$$PCl_4^{+}$$ and $$SiCl_4$$
PF5 and BrF5
$$AlF_6^-$$ and $$SF_6$$
설명
PF5
$$ \Rightarrow $$ sp3d hybridized and shape is trigonal bipyramidal.
BrF5 $$ \Rightarrow $$ 5 bond pair and 1 lone pair present so sp3d2 hybridized and shape is square pyramidal.
BrF5 $$ \Rightarrow $$ 5 bond pair and 1 lone pair present so sp3d2 hybridized and shape is square pyramidal.
