I need some help with these questions:
A. Explain the following NMR spectrum for N,N - Dimethylformamide. At room temperature, three peaks are observed:
1. 2.9 (singlet, 3H)
2. 3.0 (singlet 3H)
2. 8.0 (singlet, 1H)

As the temperature is raised, only 2 peaks are observed:
1. 2.95 (singlet, 6H)
2. 8.0 (singlet, 1H)

B. Write a complete stepwise mechanism for the reaction shown below. Show intermediate structures and electron flows with arrows. See attachment.
