determination and IR spectroscopy. Introduction: The major component of anise oil has the chemical formula C10H12O. This compound is said to be hydrogen deficient‚ meaning that it contains less hydrogen atoms than would be needed for each of the carbon atoms to have the maximum amount of hydrogen atoms attached. The IHD‚ or index of hydrogen deficiency for this molecule is 10. This indicates that there must be five rings or double bonds in the structure. Each of these would compensate for two of

ABSTRACT This study was conducted to determine the possibility of using yellow bell seeds crude extract as fuel.Mature yellow bell seeds were collected‚ cleaned‚ and ground using mortar and pestle. Water was added before the juice was extracted. To remove excess water‚ the juice extracted from the seeds was boiled and was allowed to cool. Testing on the use of the crude extract for lighting purposes then followed. Results show that it is possible to use the crude extract as substitute for kerosene

which differ only by the three-dimensional placement of the molecule’s attachments‚ which renders its mirror images to be non-superimposable. The presence of optical isomerism within a molecule is determined by the existence of a chiral centre—a carbon atom with four different groups (see Appendix‚ figure 1). Pure optical isomers have identical physical properties such as melting point‚ boiling point and density‚ as well as identical chemical properties; thus there are only two ways that they can

When compare both mechanisms instead of nucleophilic‚ SN1 the strength of nucleophilic is not important where as in SN2 needs strong nucleophilic; based on these behavior
