    Draw out the monomer, maybe it'd help for you to picture it?

    Try to establish the longest chain.

    Always look for the longest carbon chain.

    It's b and d and it's c because the longest chains is all the c in the middle there 6 of them so hexane and the short count to get to each CH3 is 2 and then 4

    Sorry man i should have been clearer okay count 4 in the middle chain going from left to right and you will get to ethyl notice there are 2 carbons on the ethyl that mean the longest "chain of carbon" is hexane as it goes c-c-c-c in the middle then up 2 c-c in the ethyl to get the longest possible chain cool

    When it comes to naming, it doesn't make sense to count the \mathrm{C_2H_5} as an ethyl group. As it's bigger than \mathrm{CH_3} it extends the chain and so you have a hexane alkane with alkyl groups attached.
