Order the steps: draw a Lewis structure

Read exercise and reference answers
Steps
  1. Count the valence electrons of every atom
  2. Arrange the atoms in their skeletal structure
  3. Place one shared pair between each bonded pair of atoms
  4. Distribute the remaining electrons as lone pairs
  5. Add multiple bonds if any atom still lacks a noble gas configuration
Count first, then place, then check. Source: syllabus Chemistry, Ch 4 Chemical Bonding and Molecular Structure.

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.
