high way lights to be switched on are when there is absolute darkness. This project gives the best solution for electrical power wastage protection. Also the manual operation of the lighting system is completely eliminated. There is provided an infrared sensor unit for deactivating an electrical appliance when left unattended by its user. The sensor

both of these compounds (Wikipedia may be helpful). What would be a good estimate for the pKa of Eugenol? Eugenol‚ pKa=10.19 at 25 degrees C. 3.) The recovered clove oil will be analyzed by Infrared Spectroscopy. What are the basic principles of Infrared Spectroscopy (can be included in the introduction if you prefer). How will we be able to distinguish between Eugenol and Acetyleugenol by IR sprectroscopy? Molecule atoms act like they are connected by flexible springs

Experiment 6 Infra-Red Spectroscopy of HCl and DCl gas Abstract Fourier-transform infrared spectroscopy has been very useful in helping scientists examining molecules of HCl and DCl. Because deuterium has a greater mass than hydrogen‚ the IR band shown for HCl is at a higher wavelength than DCl. The absorption of light in DCl was at lower frequency 1700-2200 cm-1 because D is bigger and heavier. That’s why the vibrations on the IR were shorter for DCl compared to HCl. The stretching of

AIM: TO MAKE BAKELITE USING PHENOL AND FORMALDEHYDE. INDRODUCTION: WHAT IS BAKELITE? Bakelite or polyoxybenzylmethylenglycolanhydride is an early plastic. It is a thermosetting phenol formaldehyde resin‚ formed from an elimination reaction of phenol with formaldehyde. It was developed by Belgian-born chemist Leo Baekeland in New York in 1907. One of the first plastics made from synthetic components‚ Bakelite was used for its electrical non-conductivity and heat-resistant properties
