Consider the molecule PF4Cl. (d) Would you expect the molecule to distort from its ideal electron-domain geometry? If so, how would it distort?

Hi everyone here we have a question asking us if a. S. C. L. Four br deviates from the ideal electron domain geometry. If yes. How so First let's draw lewis structure. So we have our arsenic in the middle bonded with browning With three lone electron pairs and then it is bonded with four chlorine Each with three lone electron pairs. So there are five groups surrounding the central atom which means its electron geometry is Trigana by parameter the molecular geometry is distorted because not all electron domains are alike. Our arsenic corinne Electro negativity difference is three -2 which equals one. Our arsenic bro mean electro negativity difference is 2.8 -2 which equals 0.8. The 90 degree arsenic chlorine to arsenic to be roaming. Repulsion is will be greater than the 90 degree arsenic to be roaming to arsenic bromine repulsion. So the bro mean axle to arsenic to chlorine angles will be greater than the 90 degrees. The equatorial bro meant to arsenic to roaming angles may distort slightly to make room for the actual bromine atoms that are pushed away from the equatorial chlorine atoms. So the answer is yes, There is a deviation due to the greater 90° arsenic to chlorine as To arsenic to browning repulsion is than the 90° arsenic to be roaming to arsenic to browning repulsion. Thank you for watching. Bye
