Attached proton test NMR. Can you explain how you get each answer. I don’t understand my teachers method.
Part 3: All the compounds in scheme below have identical molecular fo rmula of C.Hr.O (0 Its benzyl alcobol 2-Phemyl-1-propanol 2-Acetyl-S-norborneneProylphenol s Ck) 3,5-Dimethyl ?, 2-Pheayt 2 propano2.44 Tri-Trimethylphenapropytphenl Question 3.1: Figure 3.1 (APT) belongs to compound: a) h (e (a Figure 3.1 e pore 160 ppm Question 3.2: Figure 3.2 (APT) belongs to compound: Figure 3.22 100 ppm 160 ppm Question 3.3: Figure 3.3 (APT) belongs to compound: Figure 3.3 160 ppm 100 ppm
Explanation / Answer
3.1 APT belongs to
(a) 4-methylphenetole
Total 7 signals
1CH2 and 2C as -ve signals
2CH3 and 2CH as +ve signal
--
3.2 APT belongs to,
(h) 2,4,6-trimethylphenol
Total 7 signals
2CH3 (1 signal), 1CH3 (1 signal), 3C all apears as -ve peak
2CH as +ve signal
--
3.3 APT belong to,
