Tutor description

1. Show how the s-orbitals in the outer shells of 2 atoms can give rise to a covalent bond. Which type of covalent bond is this? 2. Show the ground state arrangement of electrons in the outer shell of a boron atom 3. Use arrows to show the direction and indicate the polarity of the dipoles in the following molecules: 4. For each of the structures in parts (a) to (c) draw the outcome of the indicated electron movements. 5. Draw the structures of the compounds formed (including the by-products) in the following reactions, the mechanism and state what type of reaction (i,e, if SN1, SN2, E1 or E2) it is.
