Why can carbon atoms form long chains and complex structures?

• Because of their high electronegativity

• Due to the ability to form double and triple bonds

• Because carbon atoms can form bonds with themselves (catenation)

• Due to their large atomic size

How does the carbon-carbon double bond in alkenes affect their chemical reactivity compared to alkanes?

• It makes alkenes less reactive

• It has no effect on reactivity

• It makes alkenes more reactive due to the presence of the π bond

• It makes alkenes more stable than alkanes

What is the significance of carbon's ability to form triple bonds, such as in acetylene (C₂H₂)?

• It makes the compound less reactive

• It allows for the formation of more rigid and linear structures

• It restricts the number of hydrogen atoms bonded to carbon

• It does not affect the chemical properties of the compound

How does the bonding versatility of carbon contribute to the complexity of biological molecules?

• It limits the types of molecules that can be formed

• It allows for the formation of diverse and complex molecules essential for life

• It only permits the formation of small molecules

• It restricts carbon to forming bonds with only a few elements
