I was drawing the number of peaks for proton NMR for a structure
Ph-C=C-C(CH3)3
the c=c bond have their hydrogens trans to each other. So when I counted the number of peaks for the =CH I got a singlet because the three methyl groups are four bonds away and the other H in the other carbon of the double bond also because we have to count a double bond as two bonds so it is four bonds away, right? However the book says that each of the hydrogens attached to the carbons of the double bond have doublets?
Could anyone explain this to me? Do we count double bonds as two bonds or no?
Thank you
