Please help! Using VSEPR theory, draw the structures for: NF3 and PI3.?
Answer:
Using VSEPR, consider the number of valence electrons of each atom involved. N has 5 valence electrons. F has 7 valence electrons.
Total number of valence electrons = 5 + 7x3 = 26
Each bond between 2 atoms has 2 electrons --> 6 electrons for 3 N-F bonds. 2 electrons: 1 from each atom --> each F has used 1 and N has used 3. Now there are 6 electrons left for each F, jst put them around F and 2 left for N.
Now there are 4 electron environments around N --> the coordination around N should be tetrahedral. However there are only 3 bonds --> the structure is trigonal pyramid.
PCl3 should be the same as NF3 because they have same number of valence electrons.
Hope it helps
