Alkenes Chemistry Quizizz

What is the first step in naming alkenes according to IUPAC nomenclature?

• Indicate the position of the double bond

• Number the carbon atoms

• Identify the longest carbon chain containing the double bond

• Name the substituents

From which end of the parent chain should the carbon atoms be numbered?

• From the end nearest to the double bond

• Randomly, as it does not matter

• From the end farthest from the double bond

• From the end nearest to a substituent

What prefix is used to indicate the presence of a double bond in alkenes?

• ane

• ene

• yne

• ine

How are substituents named and numbered in alkene nomenclature?

• Alphabetically ordered and numbered according to their position

• According to their molecular weight

• Based on their distance from the double bond

• Randomly, as it does not affect the name

What types of covalent bonds are formed in alkenes?

• Alpha and beta bonds

• Gamma and omega bonds

• Sigma and delta bonds

• Pi and sigma bonds

Which bond allows for rotation around its axis?

• Beta bond

• Pi bond

• Delta bond

• Sigma bond

How is a sigma bond formed?

• By the overlap of atomic orbitals along the internuclear axis

• By the head-to-head overlap of s-orbitals

• By the side-to-side overlap of d-orbitals

• By the sideways overlap of p-orbitals

What is the composition of a carbon-carbon double bond in alkenes?

• Two sigma bonds

• One sigma and one pi bond

• Two pi bonds

• One sigma and two pi bonds

Why can't alkenes freely rotate around the double bond?

• Due to the end-to-end overlap of p-orbitals

• Because of the side-to-side overlap of s-orbitals

• Due to the rigidity of the pi bond

• Because of the presence of a sigma bond

What is crucial for understanding the reactivity of alkenes?

• Knowing their boiling points

• Learning their solubility in water

• Understanding the formation of sigma and pi bonds

• Memorizing their molecular weights
