The carbon is the central atom, so we can draw a preliminary skeletal structure :     There is a total of 4 + 2×7 + 6 = 24 electrons, and 6 are already used for making the bond. The … Read more

Sulfur is the central atom, so we can draw a preliminary skeletal structure:     There are 3×6 + 6 = 24 electrons, and 6 of them are used to make 3 bonds. Three oxygens take 6 lone pairs and … Read more

Sulfur is the central atom:     There are 6 + 2 = 8 electrons, and 4 of them are used to make 2 bonds. The remaining four electrons go to the sulfur:     The central atom has a … Read more

Sulfur is the central atom. There are 6 + 2×7 = 20 electrons, and 4 of them are used to make 2 bonds. The two fluorines take 6 lone pairs, and the remaining four electrons go to the sulfur:   … Read more

Silicon is the central atom, so we can draw a preliminary skeletal structure:     There are 4 + 4×7 = 32 electrons, and 8 have been used to make four bonds. The remaining 24 go on the two chlorines … Read more

N is the central atom and there are 5 + 3×7 = 26 electrons. Each chlorine taking three lone pairs leaves the nitrogen with one lone pair:     The central atom has 3 atoms and a lone pair (SN … Read more

Xe is the central atom, so we can draw a preliminary skeletal structure:     There are 4×6 + 8 = 32 electrons and this time, instead of putting three lone pairs on the oxygen, we are going to directly … Read more

Sulfur is the central atom, so we can draw the skeletal structure:     There are 3×6 = 18 electrons, and 4 of them are used to make 2 bonds. The two oxygens take 6 lone pairs, and the remaining … Read more

Sulfur is the central atom, so we can draw the skeletal structure:     There are 6 + 6 + 2×7 = 26 electrons, and 6 are used to make 3 bonds. Two chlorines and the oxygen take 3 lone … Read more
