V. Lewis Dot Diagrams for Double & Triple Bonds + Polyatomic Ions

Recall…L.D.D. Steps Total # of valence electrons Total # of valence electrons needed to fulfill octet rule (Step 2 – Step 1)/2 Choose central atom (least electronegative) Connect atoms to central atom (use step 3) Place remaining valence electrons around outside atoms. Left over valence electrons go on central atom

A. Double/Triple Bonds Single covalent bond = 1 shared pair of electrons (2 total) Double covalent bond = 2 shared pairs of electrons (4 total) Triple covalent bond = 3 shared pairs of electrons (6 total)

Example #1: CO2 Total # of valence electrons Total # of valence electrons needed to fulfill octet rule (Step 2 – Step 1)/2 Choose central atom Connect atoms to central atom (use step 3) Place remaining valence electrons around outside atoms. Left over valence electrons go on central atom

Example #2: N2 Total # of valence electrons Total # of valence electrons needed to fulfill octet rule (Step 2 – Step 1)/2 Choose central atom Connect atoms to central atom (use step 3) Place remaining valence electrons around outside atoms. Left over valence electrons go on central atom

Example #3: HCCH Total # of valence electrons Total # of valence electrons needed to fulfill octet rule (Step 2 – Step 1)/2 Choose central atom Connect atoms to central atom (use step 3) Place remaining valence electrons around outside atoms. Left over valence electrons go on central atom

Polyatomic Example #1: SO42– Total # of valence electrons Total # of valence electrons needed to fulfill octet rule (Step 2 – Step 1)/2 Choose central atom Connect atoms to central atom (use step 3) Place remaining valence electrons around outside atoms. Left over valence electrons go on central atom

Polyatomic Example #2: NO– Total # of valence electrons Total # of valence electrons needed to fulfill octet rule (Step 2 – Step 1)/2 Choose central atom Connect atoms to central atom (use step 3) Place remaining valence electrons around outside atoms. Left over valence electrons go on central atom
