The video tutorial explains how to write the structural formula for one butene, emphasizing the importance of understanding the molecular formula C4H8 and its limitations in showing atom bonding. It highlights the significance of the 'ene' suffix, indicating an alkene with a double bond, and explains the placement of the double bond in the carbon chain. The tutorial also discusses the lack of geometric isomerism in one butene due to the double bond's position and provides insights into molecular models and skeletal structures.

What does the molecular formula C4H8 indicate about one butene?

• It specifies the location of the double bond.

• It describes the geometric isomerism.

• It indicates the number of carbon and hydrogen atoms.

• It shows the exact structure of the molecule.

What does the 'ene' suffix in one butene signify?

• Presence of a triple bond

• Presence of a double bond

• Presence of a ring structure

• Presence of a single bond

How many carbon atoms are present in one butene?

• Five

• Four

• Three

• Two

Where is the double bond located in the structure of one butene?

• Between the first and second carbon

• Between the second and third carbon

• Between the third and fourth carbon

• Between the first and fourth carbon

Why must a hydrogen atom be removed when forming the double bond in one butene?

• To decrease the molecular weight

• To create a triple bond

• To increase the number of carbon atoms

• To maintain the carbon's ability to form four bonds

What is the structural formula of one butene primarily concerned with?

• The number of atoms

• The arrangement of atoms

• The color of the molecule

• The weight of the molecule

What does a molecular model of one butene help visualize?

• The number of hydrogen atoms

• The weight of the molecule

• The color of the molecule

• The double bond and carbon chain

What is a skeletal structure used for in chemistry?

• To represent the molecular weight

• To simplify the representation of a molecule

• To show the color of a molecule

• To indicate the temperature of a reaction

Why does one butene not exhibit geometric isomerism?

• Because it has a triple bond

• Because the double bond is on the first carbon

• Because it has more than four carbons

• Because it is a saturated hydrocarbon

What is the role of Dr. B in the video?

• To discuss the molecular weight of butene

• To show the color changes in chemical reactions

• To demonstrate the structural formula of one butene

• To explain the concept of geometric isomerism
