Chapter 11: Problem 63

Draw structures for these compounds: (a) cyclopentane, \((\) b) \(c i s-2\) -butene, \((\) c) 2 -hexanol, (d) 1,4 -dibromobenzene, (e) 2 -butyne.

Short Answer

Expert verified
Upon drawing, five distinct structures will be observed corresponding to each of the compounds: cyclopentane, cis-2-butene, 2-hexanol, 1,4-dibromobenzene and 2-butyne respectively.

Step by step solution

01

Draw the structure for Cyclopentane

Cyclopentane is a cyclic hydrocarbon with five carbon atoms, hence draw a pentagon, each corner representing one carbon atom with two hydrogen atoms attached.
02

Draw the structure for cis-2-butene

cis-2-butene is an alkene with double bond starts from the second carbon atom. In 'cis' position, both of the higher priority groups (hydrogens in this case) are on the same side. Draw a string of four carbon atoms with a double bond between second and third carbon atom, and align the hydrogen atoms on the same side of the double bond.
03

Draw the structure for 2-hexanol

2-hexanol is an alcohol, which means it has a hydroxyl group. '2' in its name means the hydroxyl group is attached to the second carbon atom. Draw a chain of six carbon atoms with the OH group attached to the second carbon atom.
04

Draw the structure for 1,4-dibromobenzene

1,4-dibromobenzene is an aromatic compound i.e., benzene with bromine atom attached to the first and fourth carbon atoms. Draw a hexagonal benzene ring with alternating single and double bonds inside the ring, and attach Br atoms to the first and fourth carbon atoms.
05

Draw the structure for 2-butyne

2-butyne is an alkyne and has a triple bond starting from the second carbon atom. Draw a chain of four carbon atoms and place a triple bond between the second and third carbon atoms.

Most popular questions from this chapter

Draw the structures of \(c i s-2\) -butene and trans-2butene. Which of the two compounds would give off more heat on hydrogenation to butane? Explain.

Suppose benzene contained three distinct single bonds and three distinct double bonds. How many different structural isomers would there be for dichlorobenzene \(\left(\mathrm{C}_{6} \mathrm{H}_{4} \mathrm{Cl}_{2}\right)\) ? Draw all your proposed structures.

Write the structural formula of an aldehyde that is an isomer of acetone.

Octane number is assigned to gasoline to indicate the tendency of "knocking" in the automobile's engine. The higher the octane number, the more smoothly the fuel will burn without knocking. Branched-chain aliphatic hydrocarbons have higher octane numbers than straight-chain aliphatic hydrocarbons, and aromatic hydrocarbons have the highest octane numbers. (a) Arrange these compounds in the order of decreasing octane numbers: \(2,2,4-\) trimethylpentane, toluene (methylbenzene), \(n\) -heptane, and 2 -methylhexane. (b) Oil refineries carry out catalytic reforming in which a straight-chain hydrocarbon, in the presence of a catalyst, is converted to an aromatic molecule and a useful by-product. Write an equation for the conversion from \(n\) -heptane to toluene. (c) Until 2000 , tert-butylmethyl ether had been widely used as an antiknocking agent to enhance the octane number of gasoline. Write the structural formula of the compound.

2-Butanone can be reduced to 2 -butanol by reagents such as lithium aluminum hydride \(\left(\mathrm{LiAlH}_{4}\right)\). (a) Write the formula of the product. Is it chiral? (b) In reality, the product does not exhibit optical activity. Explain.
