Hello!

The question ask to find the structure of compound W with 201 g/mol molar mass from the information given in the Carbon and proton NMR spectrum.

I have extracted the information from the NMR spectrum into a table.

Since I cannot include a photo or file in this question, I will attach my table:

From Proton NMR spectrum:

Hydrogen type Chemical shift (ppm) Multiplicity Adjacent H

H_a 2.2 Singlet 0

H_b 3.5 Duplet 1

H_c 3.7 Singlet 0

H_d 5.1 Singlet 0

H_e 5.2 Duplet 1

H_f 7.2 Quartet 3

H_g 11 Singlet 0

From Carbon NMR spectrum:

Type of carbon Chemical shift (ppm)

C_p 22

C_q 68

C_r 72

C_s 126

C_t 130

C_u 138

C_v 175

Thank you so much!
