Question

The first line in the table is an example please fill in and continue the table as needed given the data

Saluent cOLLnt 93.0 80.0 X parts per Milion: 13C 20 Notes 60.0 50.0 40.0 30.0 20.0 a bundance

the molecular formula and ir information are not needed for this problem. just analyzation of thr c-nmr

Answer 1

Hi Dear Friend, the unknown is 2-octanol.

The standard ¹³C NMR has been shown below for your kind consideration.

Chemical shift, δ (ppm)	Possible functionality	Methyl, methylene, methane, 40
68.02	Aliphatic carbon	Methine (probably CH-OH)
39.42	Aliphatic carbon	Methylene (-CH2-) attached to CHOH
31.94	Aliphatic carbon	Methylene (-CH2-)
29.42	Aliphatic carbon	Methylene (-CH2-)
25.83	Aliphatic carbon	Methylene (-CH2-)
23.39	Aliphatic carbon	Methyl (-CH3) attached to CHOH
22.68	Aliphatic carbon	Methylene (-CH2-)
14.07	Aliphatic carbon	Methyl (-CH3)

200 180 160 140 120 80 60 40 20 0 100 ppm Assign. ppm OH 68.02 39.42 31.94 HOTLIWO NW in lo mo NOON

Hope this helped you!
