PRACTICE : Covalent Bonding

According to VSPER, what is the molecular shape for the Lewis structure shown? Why?

• tetrahedral, because it has three bonding pairs of electrons on the central atom

• trigonal pyramidal, because it has three bonding pairs of electrons and one lone pair of electrons on the central atom

• bent, because it has a lone pair of electrons on the center atom

• trigonal planar, because it has three bonding pairs of electrons on the central atom

What is the name of the lewis structure shown?

• nitrogen chloride

• nitrogen trichloride

• trinitrogen monochloride

• nitrogen trichlorine

What is the electronegativity difference between the N-Cl bond? Is the bond polar or non polar?

• 0, polar

• 0 non polar

• 3.0 ionic
