10 Questions
In which of the following cases can geometric isomerism be observed in alkenes according to the given text?
When each carbon of the C=C double bond is attached to two different atoms or groups
Which of the following conditions must be met for a molecule to exhibit geometric isomerism?
Each carbon of the C=C double bond should be attached to two different atoms or groups
Why does 1-butene not have geometric isomerism?
Because one carbon of the C=C double bond is attached to two identical groups
Which naming system is used to assign the geometric configuration of alkenes with three or four substituents other than hydrogen?
E-Z system
In the E-Z system, how are substituents on each of the double-bond carbons ranked?
(Lower) (Lower) (CH3 > H) (Cl > CH3) (Higher) (Higher)
In IUPAC nomenclature of alkenes, how should the parent name be determined?
By selecting the longest chain that contains the double bond and changing the ending of the name of the alkane of identical length from –ane to -ene
How should substituted cycloalkenes be numbered in IUPAC nomenclature?
Number in a way that gives the carbon atoms of the double bond the 1 and 2 positions, and gives substituent groups lower numbers at the first point of difference
What is the general formula for alkenes (Olefins)?
$C_nH_{2n}$
How are substituent groups indicated in the IUPAC nomenclature of alkenes?
By using the number of the carbon atoms to which they are attached
How should alkenes be numbered to include both carbon atoms of the double bond?
Begin numbering at the end of the chain nearer to the double bond
