Answer #1

A nitrogen atom possesses three bonding orbitals ( 2px1 , 2py1 , 1pz1 ) which are directed along the three axis at right angles. When two nitrogen atoms approach their 2 pz orbitals overlap in a head on manner to form a bond, leaving two sets of parallel orbitals 2py and 2px . Now the electron clouds in these orbitals interact to produce two bonds by the sidewise overlap.

Thus there are one sigma and two pi bonds in a molecule of nitrogen.

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...

i am taking gen chem 2- we are talking about lewis theory, valance bond theory and molecular orbital theory. We are asked What is the difference between an atomic orbital and a molecular orbital? which bonding theories are each type of orbital applicable/relevant? So I think i understand that atomic orbitals describe the probable locations of electrons in atoms and m.o. theory describes the probable locations of electrons in molecules, but im unsure if the Lewis theory or the valance...
