Write TRUE if the BOLD word/phrase makes the statement correct. Otherwise, write the correct WORD/PHRASE that will make the statement true. If there are two bold words/phrases in a number, write your answer for EACH of the bold words/phrases. 1. In the extraction of caffeine, NaOH was added to dry the collected organic layer. 2. Purification of caffeine via sublimation was possible because it has a high sublimation point at a temperature above its melting point. 3. The E/Z designation is used to describe the orientation of identical groups in alkenes.
