(a)
Interpretation:
State true or false for the following statement: The two major sources of
Concept Introduction:
Alkanes are mainly obtained by natural gas and petroleum. Alkane comes under the class of hydrocarbons having general formula
(b)
Interpretation:
State true or false for the following statement: The octane number of a particular gasoline is the number of grams of octane per liter of the fuel.
Concept Introduction:
Octane number represents the antiknocking properties of a gasoline and determined by the percentage of mixture of isooctane and normal heptane to form the knocking quality of the fuel being tested.
(c)
Interpretation:
State true or false for the following statement: Octane and 2,2,4-trimethylpentane are constitutional isomers and have the same octane number.

- Constitutional isomers are compounds which have the same molecular formula but different structural formulae. They are different compounds with different physical and chemical properties.a. Rearrange your model of n-hexane to make as many possible isomers of C6H14 as you can. Draw the structural formula and write down the IUPAC name for each isomer that you make.b. Constitutional isomers can also have different functional groups. Make all possible isomers of C3H8O. Write down the structural formulae and IUPAC names for all the compounds you make. Hint: Consider alcohol and ether functional groups.arrow_forward1. Considering compounds that have the same number of carbon atoms, explain why alkanes and cycloalkanes have different molecular formulas but alkenes and cycloalkanes have the same molecular formulas. 2. Draw the condensed or line-angle structure for an alkene with the formula C5H10. 3. Draw the condensed or line-angle structure for 4 more C5H10 isomers (2 additional alkenes and 2 cyclic isomers).arrow_forwardWhat is an isomer having the formula C6H12 ?Without using 2-hexenearrow_forward
- Gasohol is a mixture of 90% gasoline and 10% ethanol, CH 3CH 2OH. Ethanol is considered an environmentally friendly fuel additive because it can be made from a renewable source—sugarcane. Ethanol burns in air to form CO 2 and H 2O, and, like the combustion of alkanes, this reaction also releases a great deal of energy. Write a balanced equation for the combustion of ethanol.arrow_forwardPlease answer ALL parts of the question A) Alkanes: A) Draw the skeletal/line formula for octane, cyclopropane, and pentane. B) Write the molecular formula for octane, cyclopropane, and pentane. C) Draw four isomers, in any format, with the formula C6H14. B) Draw the following (in any format) and write the molecular formula: A) 3-iodo-2-methylhexane B) 1,2-dichloroethane C) 2-chloro-4-ethylnonane D) 4-isopropyldecane E) 2,2,4-tribromo-3-fluorooctane F) 1,1-difluoro-3-methylcyclohexane G) 1-ethylcyclobutane C) A) Draw the expanded structure of trans-4-chloro-2-pentene B) 3) Draw 4 skeletal isomers of C7H16 and mane them. D) Write the molecular formula of the following: A) 2-methylbutane B) 2,3-dibromo-1-pentene C) 3-bromo-1-pentyne D) 1,3-diethylbenzene E) 2,4-diisopropylbenzoic acid F) 3,3-dichloro-2,2-dimethylhexane G) 3-fluoro-2-methyl-1-butene H) 1-ethylcyclopropane I) meta-propyltoluene J) Cis-3,4-diiodo-3-heptenearrow_forwardIndicate whether each statement is true or false.
