    I just want to confirm if I'm correct on this.

    If we have the following alkane CH3CH2CH(CH3)CH2CH(CH3)CH3

    Isn't this 3,5-dimethylhexane?

    Thanks.

    you want lower numbered substituents, count from the other end, it'd be 2,4 - blah blah

    What do you mean by lower numbered substituents?

    Thanks.

    Its 2,4-dimethylhexane, you want to basically have the lowest numbers possible so if you counted from the left hand side of the chain you get 3,5- but from the right side of the chain you get 2,4 so then you go from the right side and have 2,4-dimethylhexane.
