what are the chemical shifts , multiplicity, neighboring H1, integration, and possiblr functionality or chain fragment?

this is for HNMR

Answer 1

solution : In Given HNMR (s) Chemical shift: Si = 0.89 82=1.28 $ from x-axis) multiplicity : In Long Hydro Corbon-chains or in larger lungs all the CH & CH₂ absorptions may overlap in an unresolved group and may show a singlet However Methyl hydrogens often recognised as singlets, doublets or teciplets. Two Types of Hydrogen persent (1) - CH₂ - type (giving singlet) (11) – CH₂ type (giving triplet) Integration given is 6.11 and 3:0 from this, we have 6H of type - Che which shows singlet and 34 of type - CH₂ shows triplet. So, This compound may be CH₂ (CH2) CH3 As due to symmetry, the NMR we get is of haly the compound giving two signals from 6 CH₂ hy de por & 3 CH3 hydrogen. REDML NOTE 5 PRO MIDUAL CAMERA
