Chemical Bonding and Molecular Structure — Class 11 CBSE Chemistry revision notes
A 6-page visual revision sheet for Chemical Bonding and Molecular Structure, written for Class 11 CBSE Chemistry. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Chemical Bonding and Molecular Structure sheet covers
- Why bonds form at all
- Ionic bond vs covalent bond
- Ionic (electrovalent)
- Covalent
- Lattice enthalpy and ionic bond formation
- energy released when gaseous ions pack into a solid ionic lattice (the reverse of lattice enthalpy, which NCERT defines as the energy needed to separate the solid back into gaseous ions)
- Lewis structures and formal charge
- Bond parameters
- bond length: distance between the two nuclei at equilibrium
- bond angle: angle between two bonds at a common atom
- bond order (Lewis picture): number of shared electron pairs between two atoms
- Polarity of a covalent bond
- VSEPR: predicting shape from repulsion
- VSEPR shapes by electron domain count
- Valence bond theory: overlap makes a bond
- Hybridisation: orbitals reshaped for bonding
- Reading hybridisation off a formula
- sp
- sp2
- sp3
- Worked: shape and hybridisation of NH3
- Molecular orbital theory, in brief
- Bond order from MO theory
- bond order formula
- N_2: 10 bonding, 4 antibonding electrons
- O_2: 10 bonding, 6 antibonding electrons
- O2's paramagnetism: the one thing VBT could not explain
- Hydrogen bonding
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Chemistry chapter by chapter against your real exam dates and free hours, and when the plan reaches Chemical Bonding and Molecular Structure the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
