Assertion and reason: structure

Read exercise and reference answers
Questions
  1. Reason
    Length, angle, enthalpy, order and polarity all shape how it behaves.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    Bond parameters matter for a compound's properties.
  2. Reason
    More shared pairs pull the bonded atoms closer together.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    A triple bond is shorter than a single bond.
  3. Reason
    Several structures are written on one skeletal arrangement.
    Verdict
    The assertion is false and the reason is true.
    Assertion
    Resonance means the molecule oscillates.
The reason must genuinely explain the assertion. Source: syllabus Chemistry, Ch 4 Chemical Bonding and Molecular Structure.
