CHEMICAL PROPERTIES OF ALKANES • Alkanes are generally unreactive. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. Each carbon in alkanes is sp3 hybridized. Alkenes undergo three types of main reactions, which are as follows – Many functional groups contain oxygen atoms, such as alcohols, ethers, aldehydes, ketones, carboxylic acids, and esters. The triply bonded carbon atoms in alkynes are sp hybridized, Whereas like in alkanes the single bond atoms are sp3 hybridized, causing the difference in the electronegativity. comprised of a series of compounds that contain carbon and hydrogen atoms with single covalent bonds They determine the chemical and physical properties of a compound. AlkanesPL. About this resource. Combustion of alkanes Alkanes are unreactive as a family because of the strong C–C and C–H bonds as well as them being nonpolar compounds. Lower alkanes (C 1 to C 4) are gases, middle one (C 3 to C 17) are liquids and higher are solids. All straight-chain and branched alkanes have the general chemical formula C n H 2n+2 In the case of butane, n=4, so there are 4 carbons and 2(4)+2 = 10 hydrogens. Except for the very small alkanes, the boiling pointExcept for the very small alkanes, the boiling pointrises 20 to 30 degrees for each carbon that is added torises 20 to 30 degrees for each carbon that is added tothe chain.the chain. At room temperature alkanes do not react with acids, bases, or strong oxidizing agents. Info. Functional groups Most are made from petroleum. Identify the main chemical properties of alkanes.

The functional group then provides the suffix or prefix of the name e.g –ol for alcohols, -ane for alkanes etc. Alkanes contain carbon – carbon and carbon- hydrogen single bond with average bond lengths of 154 pm and 110 pm. The C-C double bond is more reactive than a single C-C bond. You can change your ad preferences anytime. World's Best PowerPoint Templates - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from. Optical properties of SOA derived from several C 12 alkanes at 25 °C and 5 °C were determined.. SOA RI followed the order: cyclododecane < hexylcyclohexane < 2-methylundecane. Because of the presence of this partial positive charge on the carbon atom, the carbon atom is prone to getting attacked by nucleophilic reagents (electron rich species).When a strong nucleophile attacks this carbon atom, a new bond between the carbon atom and the incoming … • Different alkane structures leaded to different SOA chemical composition, which changed the RI. Learning Objective. Physical Properties of Alkanes (a) Physical State: All are colourless & possess no characteristic odour. Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. If you continue browsing the site, you agree to the use of cookies on this website. • This is because alkane molecules contain single carbon-carbon covalent bonds (C-C) and single carbon-hydrogen covalent bonds (C-H) which are strong and require a lot of energy to break. Now Alkynes are slightly electronegative in nature. Now customize the name of a clipboard to store your clips. This makes alkenes far more reactive than alkanes. Consider butane as an example: Neither positive ions nor negative ions are attracted to a nonpolar molecule.

Combustion of Alkanes All alkanes burn in air to give carbon dioxide and water. The halogen atom in haloalkanes is more electronegative than the carbon atom attached to it. As a result, haloalkanes arepolari.e., the carbon atom acquires a partial positive charge and the halogen atom acquires a partial negative charge.  Number of isomers of particular alkane increases with number of carbons. They undergo the same types of chemical reactions. Name Molecular Melting Boiling State at roomformula point (oC) point (oC) temperature&presure This is because the backbone carbon atoms in alkanes have attained their octet of electrons through forming four covalent bonds (the maximum allowed number of bonds under the octet rule; which is why carbon's valence number is 4). If the reddish-brown colour is removed from the bromine solution, the substance possesses a C=C bond. A couple of other things to note: ...
