Concept explainers

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

Use the following information to answer the question A student added bromine solution to a hydrocarbon sample that contained an isomer of C6H12 (E) in the absence of light. After shaking the sample, the student noticed that the colour of the bromine solution changed from orange to colourless. 6. An interpretation that could be made from the student's observations is that the hydrocarbon sample is and the IUPAC name of the sample could be ii.

Chemistry Which of the statements about gasoline are true? Diesel fuel has a greater proportion of straight-chain alkanes, such as octane, than gasoline. Oxygenates increase the octane rating by increasing the amount of oxygen present, thus allowing automobiles to travel longer distances on less fuel. Petroleum is a mixture of several different hydrocarbon compounds including naphthalenes and aromatics. Methyl tert-butyl ether (MTBE) is a non-hazardous substance that is often added to gasoline to increase the octane rating.
