Answer #1

Bond order of molecule = 1/2(no.of e- in B.M.O - no of e- in A.B.MO)

                                     = 1/2(8-4)

                                     = 2

Natural Bond Orbitals Natural Bond Orbitals (NBOs) convert molecular orbitals to the form of localised bonding orbitals that correspond to Lewis structures. Natural bond orbitals attempt to provide the most accurate natural Lewis structure. The NBOs are localised and are thus different to MOs - it is important not to over-interpret NBOs - NBOs give an indication of bonding and electronic structure in the framework of Lewis structures. In this exercise you will explore the bonding description of methanol from...

Krypton difluoride can be produced by arching large amounts of energy through a 1:1 mixture of Kr and F and elevated pressures. It can be stored at -78 oC, but decomposes upon heating to room temperature. Try to rationalize this by drawing an MO diagram for this linear molecule. A full MO diagram will answer this question, but an MO giagram that involves the pz orbitals on each of the atoms is sufficient to describe the bonding All the other...
