i have nooo idea how to name organic compounds or how to draw the condensed formula. the stuff in the book is not really clear. help!!!

  • chemistry -

    I'm afraid we can't help much with such a broad question. You're asking us to write a book.

  • chemistry -

    hmm...let me try to narrow it down. ok so like if i have 3,3,6-trimethylnonane, how do i know where the carbons go and how many hydrogens are attached?

  • chemistry -

    There are ALWAYS four (4) bonds to a carbon so if you can count to 4 you have that part made. A nonane is 9 C atoms long so write them out.
    Start at the left and number those carbons as 1, 2, 3, 4, 9.
    On carbon 3, you remove two H atoms and add 2 CH3 groups. On carbon 6, remove 1 H and add CH3 group and you have it. The condensed formula would be done this way.
    It's hard for me to count that high so I may have one too many or one too few carbons in the chain. One note here, when you start numbering carbon atoms as above, remember to pick the longest chain containing the most double and triple bonds.
