Understanding Stereoisomerism in Alkenes

What type of hybridization do the carbons in a carbon-carbon double bond exhibit?

• SP hybridization

• SP2 hybridization

• SP3 hybridization

• No hybridization

Why is rotation restricted around a carbon-carbon double bond?

• Because of the presence of a sigma bond

• Due to the presence of a triple bond

• Due to the lateral overlap of unhybridized p orbitals

• Because of the presence of a single bond

In the context of 2-butene, what does the term 'cis' refer to?

• Hydrogen atoms on the same side of the double bond

• Methyl groups on the same side of the double bond

• Methyl groups on opposite sides of the double bond

• Hydrogen atoms on opposite sides of the double bond

Which of the following statements is true about cis-trans isomerism?

• It only applies to disubstituted alkenes.

• It is not a type of stereoisomerism.

• It is applicable when a carbon is attached to two identical groups.

• It can apply to tri- and tetrasubstituted alkenes.

When is the cis-trans terminology not applicable?

• When the molecule is a disubstituted alkene

• When the double bond is part of a ring structure

• When one of the carbons is attached to two identical groups

• When one of the carbons is attached to two different groups
