Unformatted text preview: 2 H 6 or (H 3 C-CH 3 ) ethane – C 3 H 8 or (H 3 C-CH 2-CH 3 ) propane The C atoms are located at the center of a tetrahedron. – Each alkane is a chain of interlocking tetrahedra. – Sufficient H atoms to form a total of four bonds for each C. Example of Molecules with More Than One Central Atom Tetrahedral electronic arrangement: AB 3 U Species (One Lone Pair of Electrons on A) Some examples of molecules with this geometry are: – NH 3 , NF 3 , PH 3 , PCl 3 , AsH 3...
