    Alkanes are saturated hydrocarbons. They contain only carbon-carbon and carbon-hydrogen single bonds. They are the least reactive of the organic compounds. The main source is crude oil. Hydrocarbon- a compound consisting only of hydrogen and carbon Saturated- Contain single carbon -carbon bonds only Unsaturated-contains a C=C bond Petroleum fraction- mixture of hydrocarbons with a similar chain length and boiling range The general formula for is CnH2n+2 (for ring alkanes is CnH2n)

    phenols to be associated and‚ therefore‚ to have higher boiling points than hydrocarbons of the same molecular weight. Thus‚ phenols have a modest solubility in water. 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

    developed from knowledge of the structure of a carbon atom and how it can combine with other carbon atoms by forming covalent bonds. Alkanes Alkanes are hydrocarbons‚ which are molecules that contain only carbon and hydrogen. They are made up of carbon atoms linked together by only single covalent bonds and are known as saturated hydrocarbons. Many alkanes are obtained from crude oil by fractional distillation. The smallest alkanes are used extensively as fuels. Apart from burning‚ however
