Why it matters

This objective helps connect Nucleophilic substitution to exam-style questions, flashcards, and revision notes for Halogenoalkanes.

Quick student answer

Which of the following statements correctly explains why halogenoalkanes contain polar bonds?

Direct answer

B) The halogen atom is more electronegative than the carbon atom.

Key terms

  • Polarity: The distribution of electrical charge over the atoms in a molecule, leading to partial positive and negative charges.
  • Nucleophile: A species that donates an electron pair to form a chemical bond in a reaction.

Common trap

Confusing bond polarity with bond strength: While bond polarity affects reactivity, bond strength also depends on other factors such as atomic size and bond length.
