    Yep, which is aminoethane.
    Didn't think it asked you to name it. It said the homologous series it belongs to. Which is amine

    I wrote similarly: both covalent bonds and both a carbon is bonded to 4 other carbons

    Difference: diamond is giant lattice and graphite is not. I said carbons in diamond are tetrahedrally arranged and carbons in graphite are all in the same plane

    Don't know if that is write

    Graphite is only bonded to 3 carbons and diamond is 4

    They're both covalent aswell and both giant lattices

    I said similarities.

    They both only contain carbon. Which are convalenty bonded to each other.

    Difference: Carbon forms a tetrahederal strcuture and graphite forms layers/sheets

    Diamond forms 4 bonds with each carbon atom.

    Would I get marks for saying the carbons are in the same plane in graphite but in diamond they are tetrahedrally bonded???

    I said:

    Similarities:

    -Both covalently bond to carbon
    -both giant covalent lattices

    Differences:

    -graphite has layers diamond does not
    -diamond is bonded to 4 other carbons, graphite is only bonded to 3 carbons

    For the bit at the end, for the propagation reaction I just chose a propagation step from one of the equations. Is that correct?
