(a)
Interpretation:
The number of hydrogen atoms present in the unbranched alkane with
Concept introduction:
Alkane is made up of carbon and hydrogen atoms. These atoms form a bond with each other and with other atoms through the sharing of electrons. They do not completely donate their electrons to other atoms while forming a bond.
Answer to Problem 2.1P
The number of hydrogen atoms present in the unbranched alkane with
Explanation of Solution
The general formula of an alkane is represented as,
Where,
•
Therefore, the number of a hydrogen atom in an alkane is given with the formula as shown below,

(b)
Interpretation:
To predict the number of unbranched alkane is possible with
Concept introduction:
Alkane is made up of only carbon and hydrogen atoms. These atoms form a bond with each other and with other atoms through the sharing of electrons. They do not completely donate their electrons to other atoms while forming a bond. Alkanes are used as fuel.
Answer to Problem 2.1P
No, it is not possible to have any unbranched alkane with

- Why are different conformations of an alkane not considered structural isomers?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.
