$4.$ Assign the major diagnostic IR $($link to IR data$)$ peaks for your carboxylic acid with the corresponding functional group. You must include a description of its strength $($weak $=$w; medium $=$ m; strong $=$ s$)$ and shape $($sharp $=$ sh; broad $=$ br$)($e$.$g$.,$ C$=$O: ~$1600$ cm$-1,$ s sh$).$ Include a copy of your IR in your report $($small picture in the report is okay$).$

$5.$ Draw the structure of your carboxylic acid and label unique hydrogen atoms with a different letter. You are not required to assign specific aromatic signals to their respective nuclei, and can report these as $$aromatic protons.$$ For example, ethanol would then be assigned as: $3\mathrm{.}69$ ppm $(2$H$,$ Hb$),2\mathrm{.}61$ ppm $(1$H$,$ Ha$),1\mathrm{.}23$ ppm $(3$H$,$ Hc$).$

Assign $1$H NMR peaks Download $1$H NMR peaksof YOUR CARBOXYLIC ACID ONLY to their appropriate hydrogen atom$($s$)$ in the molecule. neeed urgently by saturday please
