For the following sequence of reactions you must choose a protecting group (PG', PG, PG) that can withstand the LiBH4 reaction conditions (strong reducing agent, strong nucleophile) and also allow you to remove PG2 in the presence of both PG¹ and PG3. You should provide both the reagents necessary to install the various protecting group as well as to remove PG². HO NH₂ CO₂Me A PG2 PG! HO PG! HO PG1 NH NH NH D CO₂Me PG³ PG3 B PG! PG 20 PG! PG₂0 ΝΗ CO₂Me LIBH4 strong reducing agent, strong nucleophile NH OH
Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).

IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
