Hi. I am reviewing some practice questions and I'm having a hard time understanding how to know which isomer would form using electrophilic aromatic substitution. I followed Huckel's rule so I know all of the options are aromatic so I have decided that is not how you figure it out. Please help! I attached a copy of the problem (the answer is A)

Hi. I just did a lab where we dehydrated 2-methylcyclohexanol. We were told it would form 1-methylcyclohexene and/or 3-methylcyclohexene and we are asked to determine the major product. I figure the major product is 1-methylcyclohexene because it is the most substituted c=c. However, we are supposed to determine it using C13 NMR. We are given the "hint" to figure out how the spectra of the 1-and 3- methylcyclohexenes would differ. I don't know how to figure this out. Any suggestions?
