Concept explainers
(a)
Interpretation:
Interpret the following statement is true or false.
‘cis and trans cycloalkane are present with same molar formula with different connectivity.’.
Concept Introduction:
The position of the substituent attached on the carbon having restricted rotation decides the cis or trans isomerism.
If the substituent facing the same side then cis isomerism is observed while the substituent facing the opposite side then trans isomerism is observed.

Interpretation:
Interpret the following statement is true or false.
‘cis can be transferred to trans isomer by rotation of the carbon single bonded to carbon.’.
Concept Introduction:

- How does the structure of a cycloalkane differ from that of a straight-chain or branched-chain alkane?arrow_forwardDistinguish between isomerism and resonance. Distinguish between structural and geometric isomerism. When writing the various structural isomers, the most difficult task is identifying which are different isomers and which are identical to a previously written structurethat is, which are compounds that differ only by the rotation of a carbon single bond. How do you distinguish between structural isomers and those that are identical? Alkenes and cycloalkanes are structural isomers of each other. Give an example of each using C4H8. Another common feature of alkenes and cycloalkanes is that both have restricted rotation about one or more bonds in the compound, so both can exhibit cis- trans isomerism. What is required for an alkene or cycloalkane to exhibit cis-trans isomerism? Explain the difference between cis and trans isomers. Alcohols and ethers are structural isomers of each other, as are aldehydes and ketones. Give an example of each to illustrate. Which functional group in Table 21-4 can be structural isomers of carboxylic acids? What is optical isomerism? What do you look for to determine whether an organic compound exhibits optical isomerism? 1-Bromo-1-chloroethane is optically active whereas 1-bromo-2-chloroethane is not optically active. Explain.arrow_forward1. a. Draw and name the five cycloalkane structures of formula C5H10. Can any of these structures give rise to geometric (cis-trans) isomerism? If so, show the cis and trans stereoisomers. b. Draw and name the eight cycloalkane structures of formula C6H12 that do not show geometric isomerism. c. Draw and name the four cycloalkanes of formula C6H12 that do have cis-trans isomers. 2. Each of the following descriptions applies to more than one alkane. In each case, draw and name two structures that match the description. (a) an isopropylheptane (b) a diethyldecane (c) a cis-diethylcyclohexane (d) a trans-dihalocyclopentane (e) a (2,3-dimethylpentyl)cycloalkane (f) a bicyclononane 3. 2. refer to the photo attached and answer the ff.3-33, 3-34arrow_forward

- Compounds X and Y both have the formula C7H14. Both X and Y react with one molar equivalent of hydrogen in the presence of a palladium catalyst to form 2-methylhexane. The heat of hydrogenation of X is greater than that of Y. Both X and Y react with HCI to give the same single C₂H₁5Cl compound as the major product. What is the structure of X? • In cases where there is more than one answer, just draw one. 7 0▾ ChemDoodleⓇ 146arrow_forward12. Write bond-line structural formulas for (a.) two primary alcohols, (b.) a secondary alcohol, and (c.) a tertiary alcohol-all having the molecular formula CaH100.arrow_forwardWhat is angle strain in cycloalkanes? Angle strain is the difference between an ideal bond angle for sp3 hybridized carbon atoms and the actual bond angle in the ring. Angle strain is the difference between and ideal bond angle for sp hybridized carbon atoms and the actual bond angle in the ring. Angle strain is the angle between C-C bonds in the cycloalkane ring. Angle strain is the angle between carbon bonds on the outer side of a cycloalkane ring. Angle strain is the difference between the C-C bond angles found in a flat ring structure and in an actual ring structurearrow_forward
