Question

SF4 is gas,SeF4 is liquid,Tef4 is solid why?

Answer 1

Hey friend

here is your answer

It happens cause it's bond Enthalpys
〰〰〰〰〰〰〰〰〰〰〰〰

In SF4 bond enthalpys are low so it is gas
〰〰〰〰〰〰〰〰〰〰〰〰
in SeF4 bond enthalpys is strong then SF4
but not strong then TeF4 so, SeF4 is liquid
〰〰〰〰〰〰〰〰〰〰〰〰
in TeF4 bond enthalpys are maximum so it is in solid form
〰〰〰〰〰〰〰〰〰〰〰〰
Thanks
