How many Signals are present present in the in the proton magnetic resonance spectrum of the compound shown below? 2MJn b c) 4 D e) 6 LOH

Identify the following spectra. Please find peaks are assigned on the spectrum (~5-6 peaks). Label the peaks on the spectrum and place the structure of the compound in the box on the lower left-hand corner of the spectrum (from the table below, no numbering scheme).

how many signal for each compound‘s HNMR ？

For each compound, give the number of 1H NMR signals and then determine how many peaks are present for each NMR signal.

IV. Draw the expected signal of the Ha proton in the following compound. H На J cis = 10 Hz H- J alilico = 1 Hz H Cl

How many ¹H peaks can occur in the ¹H NMR spectrum of the following organic compound? cl cl cl-c-c-cl | | cl cl

Question 1 Correct Answer-Label the spectra and compound OH 3 1HNMR (ppm): 4.77 (1H, br s); 3.50 (1H, quintet); 1.55 (2H, quintet); 1.40 (1H, m); 1.11 (3H, d); 0.99 (3H, t); 0.88 (3H, d) Explanation for Excellent - Draw compounds that match the other spectra. They all have the same molecular formula as above 2 IHNMR (ppm): 4.7 (1H, br s); 3.62 (2H, t); 1.58 (2H, quintet); 1.43 (2H, quintet); 1.37 (2H, quintet); 1.35 (2H, sextet); 0.88 (3H, t) IHNMR (ppm): 3.46 (2H, q); 3.35 (2H, t); 1.50 (2H, quintet); 1.46 (2H, sextet); 1.05 (3H, 1); 0.96 (3H, t) PPM 1HNMR (ppm): 3.65 (2H, m); 1.13 (12H, d)

Using the following spectra and other information provided, identify the compound. Assign pertinent peaks in the spectra. Label the peaks on the spectrum and place the structure of the compound in the box on the right side of the spectrum - Identify correct compound - label proton spectrum - label carbon spectrum
