Concept introduction:
Those compounds which have the same molecular formula but have different arrangements of atoms are known as isomers. The phenomenon is called isomerism. The isomers are generally classified as structural isomers and stereoisomers. Stereoisomers are further divided into two categories diastereomers and enantiomers.
Answer to Problem 12.18E
The alkene
Explanation of Solution
The alkene is
A compound shows cis-trans isomerism when the substituent groups on the carbon atoms that are connected via double bond are different. The alkene has the same substituted groups on a carbon atom that is on the right-hand side of the double bond. Therefore; it will not have cis-trans isomerism.

Answer to Problem 12.18E
The alkene
Explanation of Solution
The alkene is
A compound shows cis-trans isomerism when the substituents groups on the carbon atoms that are connected via double bond are different. The alkene has two different substituted groups on carbon atoms that are connected via a double bond. Therefore, it will show cis-trans isomerism. In the cis isomer, same substituted groups are on the same side of a ring or double bonds, whereas in the trans isomer same substituted groups are on a different side of a ring or double bond. Therefore, the structures of cis-trans isomers of the alkene are shown below.

A compound shows cis-trans isomerism when the substituents groups on the carbon atoms that are connected via double bond are different. The alkene has the same substituted groups on a carbon atom that is on the left-hand side of the double bond. Therefore, it will not have cis-trans isomerism.

- What is a hydrocarbon? What is the difference between a saturated hydrocarbon and an unsaturated hydrocarbon? Distinguish between normal and branched hydrocarbons. What is an alkane? What is a cyclic alkane? What are the two general formulas for alkanes? What is the hybridization of carbon atoms in alkanes? What are the bond angles in alkanes? Why are cyclopropane and cyclobutane so reactive? The normal (unbranched) hydrocarbons are often referred to as straight-chain hydrocarbons. What does this name refer to? Does it mean that the carbon atoms in a straight-chain hydrocarbon really have a linear arrangement? Explain. In the shorthand notation for cyclic alkanes, the hydrogens are usually omitted. How do you determine the number of hydrogens bonded to each carbon in a ring structure?arrow_forwardSelect those compounds that can be correctly called unsaturated and classify each one as an alkene or an alkyne: a.CH3CH2CH3f. b.CH3CH=CHCH3g. c.h.CH2=CHCH2CH3 d.i. e.arrow_forwardGasohol 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_forward
