UV Spectroscopy: UV spectroscopy is concerned with ranges from 190 to 370 nm. Compound which are colourless absorb radiation in UV range. In both UV as well as visible spectroscopy only the valence electrons absorb the energy there by molecule undergoes transition from ground state to exited state. This absorbance is characteristic and depends on the nature of the electron present. The intensity of the electron depends on the concentration and path length as given by Lambert beer’s law. Lambert

55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard reagents are alkyl magnesium halides‚ R-Mg-X were first introduced in 1900. These reagents are usually prepared by reacting one atom with one molecule or by other means magnesium and alkyl halide in the presence of dry alcohol free ether.

Ethyl acetate (systematically‚ ethyl ethanoate‚ commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3COOCH2CH3. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues‚ nail polish removers‚ and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. The combined annual production in 1985 of Japan‚ North America‚ and Europe
