Question

In the context of hydrocarbons, consider the following statements,

i) Compounds with single bonds are more stable than those with double or triple bonds.

ii) During the formation of the double or triple bonds, the spatial orientation of other orbitals changes and interelectronic repulsions increase.

• A. Only i) is correct
• B. Only ii) is correct
• C. Both i) and ii) are correct but ii) dosen't explain one
• D. Both i) and ii) are correct and ii) explain one

Answer 1

The correct option is D

Both i) and ii) are correct and ii) explain one

Both statements are accurate if we consider simple hydrocarbons. Compounds with single bond are stable than those with double or triple bonds because, during the formation of the double or triple bond, the spatial orientation of other orbitals changes and interelectronic repulsions increase.

For example, cyclohexane is more stable than benzene. Also, butane is more stable than butene, which in turn is more stable than butyne.
