a) Predict the electron-domain geometry around the central
S atom in SF2, SF4, and SF6.

Accepted Answer

Hi everyone here we have a three part question. So we're gonna start with a what is the electron domain geometry around selenium and selenium di chloride. So let's draw out our Lewis structure here. We have selenium in the middle With two long pairs And it is bonded to two chlorine each with three lone pairs. So there are four electron groups around selenium, meaning it is an A. X. Four molecule giving it a tetra. He'd real electron domain geometry. Next we have b what is the electron domain geometry around selenium in selenium tetrachloride. So we have selenium in the middle again and it will have one lone pair And then it will be single bonded to four chlorine Each with three long pairs. So it has five electron groups around selenium Making it an X. five molecule and giving it a Trigon all by cram it'll electron geometry. So our answer is for the first two are tetra he'd rel and Trigano by parameter. And now let's look at see what is the electron domain geometry around selenium and selenium hexafluoride. So we're again going to draw the electron geometry. So we're going to have our selenium in the middle surrounded by six chlorine each with three long pairs. So it has six electron groups around selenium Making it an AX six molecule and giving it an Octa he drel electron domain geometry. And that is our last answer. Thank you for watching. Bye
