  1. 4-ethyl-3,4,6-trimethyloctane

 

    1. should be 2-methylbutane; counting from wrong end.
    2. should be 3-methylhexane; you can’t have 1-methyl anything
    3. needs 2 numbers if its “di”-methyl
    4. should be 2-methylbutane; longest chain is 4 carbons, not 3 carbons; 2-ethyl is impossible.
