Ensemble The Piphat ensemble is made up of percussion and wind instruments. The most common Piphat is known as the piphat mai khaeng. This ensemble uses the Xylophones‚ such as the Ranat Ek‚ and Ranat Ek Lek‚ and also uses wind instrumenst such as the Pi Nai. ♦ Though the Piphat ensemble is centuries old‚ its current instrumentation is established in the 1800s. ♦ There is no standard pitch reference for Thai instruments; instead‚ each ensemble is tuned to itself. ♦ It is considered the primary form of

CLASSIFICATION TESTS FOR ORGANIC HALIDES James Anand L. Regala‚ Sabrina Nicolle G. Sarte‚ Ann Michelle Siao‚ Michael Sibulo‚ Victoria Tan Group 8 2C Pharmacy Organic Chemistry Laboratory ABSTRACT This experiment is done to classify organic halides. Most organic halides are synthetic and are not flammable. One way to classify organic halides is by classifying its -carbon atom as primary‚ secondary or tertiary. If the -carbon is attached to one R group‚ it is then primary. If the -carbon is

polar aprotic solvent and requires the presence of a strong nucleophile. For this experiment‚ you will use sodium iodide (NaI) in acetone. You will test nine substrates (Figure 1) under each of these two reaction conditions to see which compounds will do SN1‚ SN2‚ neither reaction or both. You will observe the formation of a precipitate upon reaction. For the SN2 reaction‚ NaI is soluble in acetone but the byproducts of reaction‚ NaCl or NaBr (depending on the leaving group of each compound) are
