Explanation:
B. The writer didn't mention anything significant .
Answer:
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.
T = ??°K, V = 15.50L, P = 870torr
PV = nRT, with P in atm, 760torr/atm
T = PV / nR = 1atm/760torr × 870torr×15.5 ÷ .0821 = 216.12 °K
