    Ok, so i get that the number of carbons in the longest chain gives u the stem

    ie 1 = meth
    2 = eth
    3 = cant remember
    4 = but
    5 = pent
    6 = hex
    7 = hept
    8 = oct
    9 = non
    10 = dec



    Is that 2 methyl pentane or 4 methyl pentane? =/ (as in which end do you count from?)

    I got the ment from the 5 carbons in tha main chain and the metyl from the 1 carbon on the side chain.

    Thanks in advance


    Thanks

    Sorry if thats confusing :P

    That's 2-methylpentane; you always count from the end that gives you the shortest distance.

    It's 2-methylpentane. You always designate carbon number 1 so that you get the lowest possible numbering in the molecule name.

    yes, it's 2-methylpentane

    nb: 3 carbons = prop (propene/propane etc)

    Its 2 methyl-pentane

    You count from the side that gives you the smallest number the group it attached (if that mkaes sense - so in this case its 2 not 4)
