Question 1 2 pts A signal of hydrogens with three neighbors will be split into a triplet O doublet quartet O singlet Question 2 2 pts 13C NMR does not exhibit C-C coupling, which results in each signal being a singlet. Why? 18.15C bond lengths are much longer than c ' bonds, resulting in no coupling Broadband hydrogen decoupling removes internuclear peak splitting The low natural abundance of C versus the high natural abundance of 'h means that 19.1 coupling is very unlikely The relative high electronegativity of ic relative to that of 'H means electrons are drawn more tightly to the C nucleus and will not couple
