26 - Back Bonding | Application of Back Bonding | Chemical Bonding | JEE Mains & Advanced | NEET

Lecture - 26 of Chemical Bonding | Zero to Advanced Series, where we discuss Back Bonding in detail, starting from the concept of back bonding in BF₃, its conditions, and its important effects. Along with the theory, we solve important conceptual & exam-oriented questions including the Lewis acid strength of BF₃, BCl₃, BBr₃ & BI₃, comparison of B–F bond length & bond order in BF₃ and BF₄⁻, coordinate bond formation in BF₃, aromaticity of Borazine (B₃N₃H₆), comparison of basic strength of trisilylamine [N(Si₃H)₃] & trimethylamine [N(CH₃)₃], and stability comparison of CH₂⁻–F and CH₂⁻–Cl. This lecture is useful for JEE Main & Advanced, NEET & Olympiad preparation, with concepts explained from basic to advanced level.
