Molecular Formula: H3CCCH Hybridization of Central atom: ? Electon geometry: ? Molecular geometry: ? Bond Angle(s) (list all if there are more than one): I don't really get it because all three Carbons are the central atom.
5. Give the hybridization, electron pair geometry, and molecular geometry of the centrail atom(s) in the structures in question 3, 6. For any molecule in question 1 containing lone pair electrons on the central atom, look up and record the literature values for the bond angles of the molecular structure 7. Read the section on hybrid orbitals in your book. Explain how hybrid orbitals are formed using the sp' hybrid orbitals as the example. 8. Double and triple bonds also...
