    therefore‚ depicting an carbonyl functional group. Table 2 also demonstrates a peak was present at 1583 cm^(-1)‚ this peak represents an aromatic ring being present in the molecule due to an aromatic ring’s literature value ranging from 1600-1475 cm^(-1). N‚N-diethyl-toluamide’s literature IR spectrum has a peak at approximately 1475 cm^(-1)‚ therefore‚ representing an aromatic ring (Webbook.nist).

    Phenol‚ also known as carbolic acid‚ is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C6H5) bonded to a hydroxyl group (-OH). It is mildly acidic‚ but requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar‚ but today is produced on a large scale (about 7 billion kg/year) from petroleum. It is an important industrial commodity as a

    Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 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

    Although phenols are structurally similar to alcohols‚ they are much stronger acids‚ however they are weaker acids compared to carboxylic acids. In the experiment‚ the following samples of aldehydes are used‚ 1) Benzaldehyde It is the simplest aromatic aldehyde. It is employed to confer almond flavor. It is used chiefly as a precursor to other organic compounds‚ ranging from pharmaceuticals to plastic derivatives. 2) Formaldehyde It is the simplest form of aldehyde‚ also called methanal
