How is vbt different from lewis concept
Web3 sep. 2024 · According to valence bond theory (VBT), a covalent bond forms from the physical overlap of half-filled valence orbitals in two atoms. On the other hand, according to the molecular orbital theory (MOT), individual atoms combine to form molecular orbitals. Why did VBT fail? It fails to explain the tetravalency of carbon. WebGive the main feature of Lewis approach of chemical bonding. [1] Write electron dot structure (Lewis structure) of Na, Ca, B, Br, Xe, As, Ge, N3-. [1] Define electrovalent bond. [1] Give the octet rule in short. [1] Define an ionic bonding. [1] Which one of the following has the highest bond order? N 2, N2 + or N2-. [1] Define bond order. [1]
