SOME IMPORTANT POINTS: 1. more is the S character more is is the bond angle, more is electronegativity and thereby more is the acidic character. 2. vont Hoffs factor i is one for non-electrolytes. 3. fart gas the mixture of Nitrogen, Oxygen, Methane, CO2 etc. 4. Electrolytic conduction increases with increase in temperature but Electronic conduction decreases with increase in temperature. 5. it is important to note that mass of neutron ≈ mass of proton ≈ 1 AMU ≈ 1.6 × 10-²⁴ g 6. more is the oxidation state, more is acidic. e.g, HClO4 is more acidic than HClO3 . So, HClO4>HClO3>HClO2>HClO. 7. NH3 has greater dipole moment than NF3. 8. Ortho compound has always greater dipole moment than meta compound. 9. alkaline KMnO4 is called Bayers reagent. 10. a) maximum no. of electrons in a shell is 2n² b) maximum no. of electrons in subshell is 4L plus 2 c) maximum no. of electrons in orbital is 2 d) number of orbitals in a shell is n².
