NMR spectrum - how to determine splitting patternWatch
2.. how do i know if its a ketone or aldehyde from a nmr spectrum?
There's a triplet @3.6 (3rd H from left) with 2 adjacent H (on 2ndH). Shift due to H-CO
Singlet @2.4 = 4th OH do no split or cause splitting
Quintet @1.6 = 2nd with 5 adj (3 on 1st & 2 on 3rd)
Triplet @0.9 = 1st with 2 adj
Aldehydes have a HC=O peak at 9-10, ketones do not.
