Question

For each of the following molecules, write the Lewis structure(s), predict the molecular structure (including bond angles), give expected hybrid orbitals on the central atom, and predict the overall polarity. 

       a. OF2    b. AsF5   c. IF5   

Answer 1

A) OF₂ - sp3 hybridization, bent, bond angel - 103^o, polar

B) AsF₅ - sp3d hybridisation, trigonal bipyramid, nonpolar

C) lF₅ - sp3d2 hybridisation, square pyramidal, polar
