Vegetative reproduction (vegetative propagation‚ vegetative multiplication‚ vegetative cloning) is a form of asexual reproduction in plants. It is a process by which new individuals arise without production of seeds or spores. It can occur naturally or be induced by horticulturists. Although most plants normally reproduce sexually‚ many have the ability for vegetative propagation‚ or can be vegetatively propagated if small pieces are subjected to chemical (hormonal) treatments. This is because meristematic

Chem 3418 Organic Chemistry Laboratory I Acid Base Review Definition In general‚ an acid is a substance that can donate a proton (H+) and a base is a substance that can accept a proton. Any proton in an organic molecule can potentially be donated. The most acidic proton in a molecule would be donated first. Any lone pair in an organic molecule can act as the proton acceptor. An acid (HA) reacts with a base (in this case H2O) to form the conjugate base of the acid (A-) and the conjugate acid of the

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
