Which C-X bond has the highest bond energy per mole ?
Correct answer: A. C-F
- A. C-F
- B. C-C
- C. C-Br
- D. C-I
Explanation
Among the listed bonds, C-F has the greatest bond energy because fluorine forms a short, strong bond with carbon due to its small atomic size and effective orbital overlap. Students may choose C-I because iodine is a heavy halogen, but the larger iodine atom forms a longer and weaker C-I bond.

About Nomenclature, Structure and Reactivity
Alkyl halides are named by selecting the longest carbon chain and locating the halogen substituent, while their structures are classified as primary, secondary or tertiary. Their reactivity includes nucleophilic substitution and elimination, with the behaviour of leaving groups and the distinction between SN1 and SN2 mechanisms linked to substrate structure.
