(a)
Interpretation:
The given statement is true or false should be determined.
The IUPAC name of an alkene is derived from the name of the longest carbon chain that contains the carbon-carbon double bond.
Concept Introduction:
The IUPAC name is the set of rules that is created and applied by the International Union of pure and Applied Chemistry to generate systematic proper name of chemical compounds. This nomenclature is used to describe and identify the type and position of
Cis-trans stereoisomerisms are seen in alkenes compounds. Due to presence of two different groups bonded to carbon of carbon-carbon double bond, restricted action occurs in it and results into cis-trans isomerism. If same groups are present on the same side, then the isomer is called as cis-isomer and the same groups are present on different side the isomer is called as trans-isomer.
Answer to Problem 11P

Concept Introduction:
The IUPAC name is the set of rules that is created and applied by the International Union of pure and Applied Chemistry to generate systematic proper name of chemical compounds. This nomenclature is used to describe and identify the type and position of functional groups, side chains, double or triple bonds etc. in alphabetical order to provide systematic name to compound.
Alkenes are the compounds with very weak London dispersion forces and are nonpolar. They contain same skeleton structure and physical properties like alkanes but liquid at room temperature.
Cis-trans stereoisomerisms are seen in alkenes compounds. Due to presence of two different groups bonded to carbon of carbon-carbon double bond, restricted action occurs in it and results into cis-trans isomerism.
If same groups are present on the same side, then the isomer is called as cis- isomer and the same groups are present on different side the isomer is called as trans- isomer.
Answer to Problem 11P
The given statement is false.
Explanation of Solution
IUPAC name of
Therefore, the given statement is false.
(c)
Interpretation:
The given statement is true or false should be determined.
2-Methyl-2-butene shows cis-trans isomerism.
Concept Introduction:

If same groups are present on the same side, then the isomer is called as cis- isomer and the same groups are present on different side the isomer is called as trans- isomer.
Answer to Problem 11P
The given statement is false.
Explanation of Solution
2-Methyl-2-butene contains two methyl groups present on carbon atom of carbon-carbon double bond other carbon contains also methyl group.
To get cis and trans isomers, two different groups should be present on the carbon atoms of the carbons with double bond.
Thus, the statement is false.
(d)
Interpretation:
The given statement is true or false should be determined.

Answer to Problem 11P
The given statement is false.
Explanation of Solution
Following are the structures of the isomers of 1,2-dimethylcyclohexane. Form this, we can see that all four atoms of carbon-carbon double bond are lying in same plane.
Therefore, the given statement is false.

Answer to Problem 11P
The given statement is false.
Explanation of Solution
Following is the structure of 1,3-Butadiene. There are no stereocenters are present in the structure of 1,3-Butadiene. There should be presence of different groups for isomerism.
Therefore, the given statement is false.
