Problem: Determine the molecular geometry for SF4.

FREE Expert Solution

Draw the Lewis structure of SF4 to identify its molecular geometry. When drawing Lewis structure, count the valence electrons of each atom present then count the total number of electrons in the compound.

S → Group 6A → 6 valence e-

F → Group 7A → 7 valence e- x 4 = 28 e-

Total valence e- = 34 e


S → least electronegative atom → central element

→ prefers to have 1 bond and complete octet
