For each of the following molecules or molecular ions, give the steric number, sketch and name the approximate molecular geometry, and describe the direction of any distortions from the approximate geometry due to lone pairs. in each case, the central atom is listed first and the other atoms are all bonded directly to it.(a) teh2(b) asf3(c) pcl5(d) xef6

if you mean hydrogen and oxygen then water is the product

it means there are 3 atoms of oxygen
