Vedantu 9,10 &11・2 minutes read
Nikita ma'am from Vedanta explains chemical bonding, covering Lewis rule, ionic bonds, polar and non-polar covalent bonds, and molecular orbital theory. The session emphasizes understanding bond theories for answering questions, including topics like Lewis Dot structure creation, bond parameters, VSEPR theory, and Valence bond theory, concluding with stability and magnetic properties related to bond order.
Insights
Chemical bonding is the attractive force that holds atoms together to form molecules, with Lewis symbols representing valence electrons and the octet rule guiding stable octets. The session covers various bond types, including ionic and covalent bonds, emphasizing electron transfer and sharing, and explains concepts like polar and non-polar covalent bonds, formal charge calculation, and limitations of the octet rule.
Molecular geometry is determined by the VSEPR theory, considering valence shell electron pairs' repulsion, leading to different shapes like linear, tetrahedral, trigonal, and octahedral. The text also explores resonance structures, dipole moments, and Fajan's rule, detailing factors influencing ionic bond formation, bond parameters like length and angle, and bond enthalpy. Valence bond theory elucidates sigma and pi bonds' formation, with bond order indicating bond strength and stability, affecting bond length and magnetic properties based on paired or unpaired electrons in molecular orbitals.
