Alkenes & Alkynes

What type of bonds do alkanes have?

• Double bonds

• Single bonds

• Triple bonds

• No bonds

Which type of fat is more chemically stable?

• Omega-3 fats

• Trans fats

• Unsaturated fats

• Saturated fats

What is the main reason alkenes are more reactive than alkanes?

• Presence of σ bonds

• Presence of triple bonds

• Presence of π bonds

• Lack of hydrogen atoms

How does cis-trans isomerism affect molecules?

• It makes them non-reactive

• It alters their physical and chemical properties

• It changes their molecular formula

• It increases their molecular weight

What process is used to convert unsaturated fats into saturated fats?

• Hydrogenation

• Polymerization

• Oxidation

• Hydration

Why are trans fats considered harmful to health?

• The body cannot properly metabolize them

• They are high in calories

• They contain no nutrients

• They are too reactive

What is a characteristic feature of omega-3 fatty acids?

• Multiple triple bonds

• A triple bond at the end

• No double bonds

• A double bond at the third carbon from the end

Which type of reaction do π bonds in alkenes and alkynes typically participate in?

• Elimination reactions

• Substitution reactions

• Addition reactions

• Condensation reactions

How does the structure of a molecule influence its interaction with biological systems?

• Through its molecular weight

• Through its spatial arrangement

• Through its color

• Through its density

What is the impact of fatty acid saturation on health?

• Saturated fats are more fluid

• Unsaturated fats are chemically stable

• Saturated fats can lead to artery blockage

• Unsaturated fats are solid at room temperature
