Question

There are certain trends with which you should become very familar (recognizing these trends will save you time!) This part of the question is dedicated to that task. a) Whenever you see 9 or a multiple of 9 in the integration ratio, which group should you first consider for being responsible for that signal. b) Whenever you see a quartet and triplet on a spectrum, which group should you first consider for being responsible for those signals? c) Whenever you see septet and a doublet on a spectrum, which group should you first consider for being responsible for those signals? d) Whenever you see 6 or a multiple of 6 in the integration ratio, which group should you first consider for being responsible for that signal e) Whenever you see 3 as the actual number of protons for a given signal, which group should you first consider for being responsible for that signal

Answer 1

isopropl

d) Whenever you see 6 or a multiple of 6 in the integration ratio, which group should you first consider for being responsible for that signal

isopropl

e)Whenever you see 3 as the actual number of protons for a given signal, which group should you first consider for being responsible for that signal
