What is high octane number?
Retail gasoline stations in the United States sell three main grades of gasoline based on the octane level: Regular (the lowest octane fuel–generally 87) Midgrade (the middle range octane fuel–generally 89–90) Premium (the highest octane fuel–generally 91–94)
What is petrol octane number?
Regular petrol is rated at 91 octane. “There is a long-time demand from SIAM (Society of Indian Automobile Manufacturers) for 95 octane gasoline,” said Vaidya. However, with the monumental challenge of switching to low-sulphur fuels during the transition to BS6, the oil industry had decided to stick to 91 octane.
What are the properties of heptane?
Heptane Properties. It belongs to the family of Acyclic Alkanes. In terms of its appearance and physical characteristics, heptane is a clear and colorless liquid with an odor similar to petroleum. It is insoluble in water and less dense than water, with a flash point of 25° F and vapors that are heavier than air.
What are position isomers?
Positional isomers are constitutional isomers that have the same carbon skeleton and the same functional groups but differ from each other in the location of the functional groups on or in the carbon chain.
What are the constitutional isomers of pentane?
Pentane has 3 constitutional isomers. N-pentane,2-methylbutane,2,2-dimethylpropane.
What are the possible isomers for pentane?
Hence the possible isomers are: n-Pentane (Maximizing the number of carbon atoms in the main chain) Isopentane or 2-methylbutane (Shortening the main chain to four C-atoms and looking for positions to place one methyl group) Neopentane or 2,2-dimethylpropane (Main chain has three carbons in this case)
