WebVideo transcript. - [Voiceover] For this NMR, the molecular formula is C9H10O, let's go ahead and calculate the hydrogen deficiency index. So if we have nine carbons, the maximum number of hydrogens we can have, is two times nine plus two. And two times nine, plus two, is equal to 20, so for nine carbons, 20 hydrogens is the maximum number. WebSep 2, 2024 · Call Centre: 0800 202 933 [email protected] Switchboard: 012 357 3000.
