    en.wikipedia.org/wiki/4-Nitrobenzaldehyde

    4-Nitrobenzaldehyde is an organic compound with the formula O 2 NC 6 H 4 CHO. It is one of three isomers of nitrobenzaldehyde. It contains a nitro group para-substituted to an aldehyde. 4-Nitrobenzaldehyde is obtained by oxidation of 4-nitrotoluene or hydrolysis of 4-nitrobenzalbromide: [3] O 2 NC 6 H 4 CHBr 2 + H 2 O → O 2 NC 6 H 4 CHO + 2 HBr

  9. Chemical shift - Wikipedia

    en.wikipedia.org/wiki/Chemical_shift

    In proton NMR of methyl halides (CH 3 X) the chemical shift of the methyl protons increase in the order I < Br < Cl < F from 2.16 ppm to 4.26 ppm reflecting this trend. In carbon NMR the chemical shift of the carbon nuclei increase in the same order from around −10 ppm to 70 ppm. Also when the electronegative atom is removed further away the ...
