Question

Or none of the above

What type of proton NMR signal will proton H_ give rise to? singlet doublet triplet quartet quintet sextet septet octet nonet

Answer 1

Answer -

Please carefully observe the vicinity proton of H_L , l hereby circled out all vicinity protons that would coupled with H_L proton. Plz see attached photo -

proton NMR signey will proton HL Q> What give type rise of to ?

All protons which are 1-2 bond vicinity with respect to H_L proton gets coupled , as result H_L gives sextet peak. H_L proton surrounded by five proton ,so each proton coupled with H_L gives sextet peak based on n+1 rule, here n= 5 , so multiplicity of H_L proton ,

would be = 5+1

= 6 lines

So correct option is ' sextet '
