In class, we're tackling IUPAC and the following one has me boggled because I don't think we've covered this type of structure yet with a 't' and 'iso' in it. I'm confused how to solve this. The online quiz asks for the correct IUPAC name and why it is incorrect. "Each of the following names is an incorrect IUPAC name. State why the name is incorrect. (Select all that apply.) Indicate, if possible, what compound the namer of the compound had in mind and give the correct IUPAC name. (d) 5-t-butyl-1-isopropylcyclopentene reason for error -The longest carbon chain is not used -The sum of the substituent positions do not add up to lowest possible number. -The double bond in the ring does not contain the number one carbon. -Molecule has no cis-trans isomers. -The wrong name for the benzene derivative is used
