The physical properties of alkenes and alkynes are generally similar to those of alkanes or cycloalkanes with equal numbers of carbon atoms.

Physical properties

Hydrocarbons are compounds made up of carbon and hydrogen and these hydorcarbons form important fuels like petroleum,diesel etc. Saturated hydrocarbons : The hydrocarbons that has carbon - carbon single bond. Unsaturated hydrocarbons : The hydrocarbons that has carbon -carbon double or triple bond. Example :. Representation : C n H 2n.

This carbon-carbon double bond changes the physicals properties of alkenes. Hydrogenation is used in the manufacture of margarine from vegetable oils. Their reactivity, however, is significantly different. The first four members of straight chain alkanes — methane, ethane, propane and butane are gases. Physical properties of alkenes are quite similar to those of alkanes. When the skeleton chain electrons of the alkane are randomly occupied by other heteroatoms, the original name is modified with the heteroatom prefix but the total number of heteroato… Internal alkynes are compounds in which the triple bond is between two carbon atoms, none of which are terminal. Terminal alkynes are the most acidic group in hydrocarbon family.

Lab Reports. This week you will be doing experiments on several different hydrocarbons - compounds composed of carbon and hydrogen atoms. The largest database [1] of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. Solubility in water, and organic solvents, combustibility, and reactivity with various chemical reagents will be examined. Other hydrocarbons exhibit the same trends. The study of hydrocarbons can provide insight into the chemical properties of other functional groups and their preparation. Lab Report on Hydrocarbons.

Alkynes are organic molecules with carbon-carbon triple bonds. They are unsaturated hydrocarbons with the empirical formula of CnH 2n The simplest alkyne is ethyne which has the common name acetylene. Acetylene is a common name to memorize. It is important to distinguish between terminal and internal alkynes because they can undergo different patterns of reactivity. The sp hybridization of the carbon-carbon triple bond results in the perpendicular orientation of the sigma bond and two pi bonds.

Make sure that your printout includes all content from the page. If it doesn't, try opening this guide in a different browser and printing from there sometimes Internet Explorer works better, sometimes Chrome, sometimes Firefox, etc. Hydrocarbons are the simplest organic compounds, but they have interesting physiological effects. These effects depend on the size of the hydrocarbon molecules and where on or in the body they are applied.
