Look at the given spectroscopy data. How many degrees of unsaturation are present in this molecule? The IR at 1735 cm-1 is indicative of a type bond and when combined with the 13C NMR signal at 172 ppm and general H NMR is indicative of a(n) functional group. The 1HNMR peak at 6.3 ppm and broad signal at 3325 cm-1 in the IR is indicative of a(n) that is bonded to a

Explanation:

Degree of unsaturation can be calculated by the formula

DU = (2C+2+N-X-H)/ 2 where

C is the number of carbons

N is the number of nitrogens

X is the number of halogens (F, Cl, Br, I)

H is the number of hydrogens. Oxygen and sulfur are not included in the formula because saturation is unaffected by these elements

So for C18H29NO2

DU = (36+2+1-29)/ 2 = 05.

The IR at 1735 cm-1 is indicative of a carbonyl type bond and when combined with the 13C NMR signal at 12 ppm and general H NMR is indicative of a (n) ester funtional group.

The HNMR peak at 6.3 ppm and broad signal at 3325 cm-1 in the IR is indicative of a (n) amine that is bonded to sp2 hybridized central atom.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
