NCERT Solutions for Class 11 Chemistry Chapter 4: Points to Remember

Some of the important points from Class 11 Chemistry Chapter 4 are as follows:

  • A chemical bond is the force that holds the atoms in a molecule together.
  • The Lewis symbol represents valence electrons as dots surrounding the element symbol.
  • Formal charge on an atom in a molecule/ion = Total no. of valence electrons in free atom − Total no. of electrons of lone pairs −12 (Total no. of shared electrons).
  • Magnitude of repulsions: Lone-Pair-Lone Pair > Lone Pair-Bond Pair > Bond Pair-Bond Pair.
  • Dipole moment: μ=q × d
  • Sigma and pi bonds: It can be s–s, s–p or p–p
  • Calculation of total number of bond pairs (B):  L=T–B.
  • If A represents central atom, B bond pair and L lone pair, we have AB2 (linear).
