Hi, I need help in naming this compound. Firstly, can someone explain to me what it means my C(CH3)3. Does it means its a C connected to 3 methyl groups? I would name it 2-bromo-4-dimethyl-6-trimethyloctane but apparently the answer i was given is : 7-bromo-3-ethyl-2,2,5,5-tetramethyloctane or 2-bromo-6-tert-butyl-4,4-dimethyloctane Can someone explain to me why is it name that way? Thanks.
