Question

Select the correct ranking of decreasingX-A-X bond angles for the following species.
CO2 > PbCl2 > PCl3 > BrF5
CO2 > PCl3 > PbCl2 > BrF5
PCl3 > PbCl2 > CO2 > BrF5
PbCl2 > PCl3 > BrF5 > CO2
PbCl2 > CO2 > PCl3 > BrF5 Select the correct ranking of decreasingX-A-X bond angles for the following species.
CO2 > PbCl2 > PCl3 > BrF5
CO2 > PCl3 > PbCl2 > BrF5
PCl3 > PbCl2 > CO2 > BrF5
PbCl2 > PCl3 > BrF5 > CO2
PbCl2 > CO2 > PCl3 > BrF5

Explanation / Answer

We Know that :    CO2 molecule has SP hybridisedthe bond angle in CO2 has 1800      PbCl2 molecule hasSP2 hybridisation the molecule has planar geometrywith bond angle of 1200       PCl3   molecule has SP3 hybridisation with one lone pair of electron so the bond angle isfound to be 1070      BrF5  molecule has d2SP3 hybridisation whichTrigonal bipyramidal geometry with bond anle of 900 , 1200         SO the optionis   CO2 > PbCl2 > PCl3 > BrF5
        SO the optionis   CO2 > PbCl2 > PCl3 > BrF5
