Chemical Bonding — Class 11 Maharashtra HSC Chemistry revision notes

A 8-page visual revision sheet for Chemical Bonding, written for Class 11 Maharashtra HSC 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 sheet covers

• Kossel-Lewis approach
• Ionic bond: NaCl and CaCl2
• Ionic bond vs covalent bond
• Ionic
• Covalent
• Ionic solids and lattice enthalpy
• Lattice enthalpy, some values
• Covalent bond and Lewis structures
• Formal charge
• formal charge on an atom in a Lewis structure
• CO, structure C≡O: formal charge on C
• Limitations of the octet rule
• VSEPR: predicting shape from repulsion
• VSEPR shapes, by lone pair count
• Valence bond theory
• Hybridisation
• Worked: BeCl2, why hybridise at all
• Molecular orbital theory
• Bond order from MO theory
• bond order
• H_2, config σ1s^2: 2 bonding, 0 antibonding
• N_2, config through σ2p_z^2: 10 bonding, 4 antibonding
• O_2, two electrons singly fill π^*: 10 bonding, 6 antibonding
• F_2, config through π^*2p^4: 10 bonding, 8 antibonding
• O2's paramagnetism
• Bond parameters
• bond length, H-Cl
• bond angle, H-O-H
• bond enthalpy of H_2 (dissociation energy, since H_2 is diatomic)
• average O-H bond enthalpy in H_2O, from two unequal successive steps
• Dipole moment
• Fajans' rules: covalent character in an ionic bond
• Resonance
• 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 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.
