Draw the Lewis structure of CH₂CCBr and then choose the appropriate set of hybridization states for the three central atoms. Your answer choice is independent of the orientation of your drawn structure. + A) sp²/sp/ sp² B) sp² / sp² / sp³ C) sp³/sp/sp D) sp²/sp² / sp² E) sp / sp³ / sp³

Aluminum chloride, AlCl₃, is used in a variety of organic reactions as a Lewis acid. Although it adopts a more complex geometry in the solid state, consider it as a single molecule (i.e., in the gas phase). Given the electron configuration of Al is [Ne]3s²3p¹, how many valence electrons does Al have?

How can I use the Born Haber cycle to establish the lattice energy of CsCl (s)from the following data: ΔHf° [CsCl(s)] = -442.8 kJ/mol; enthalpy of sublimation of Cesium is 78.2 kJ/mol; enthalpy of dissociation of Cl2 (g) = 243 kJ/mol Cl2 ; IE1 for Cs(g) = 375.7 kJ/mol; electron affinity enthalpy-EA1 for Cl(g) = -349kJ/mol.

2. For each pair, choose the compound with the smaller lattice energy, and explain your choice: (a) Cas or Bas (b) NaF or Mgo

What is noble gas electron configuration of Zn2+ ?

Consider the following electron configuration:(σ3s)2(σ3s*)2(σ3p)2(π3p)4(π3p*)4Give four species that, in theory, would have this electron configuration.

Use the following data to estimate AH; for potassium bromide. K(s) + Br2 (9) - KBr(a) Lattice energy -671 kJ/mol Ionization energy for K 419 kJ/mol Electron affinity of Br -325 kJ/mol Bond energy of Br2 Enthalpy of sublimation for K 193 kJ/mol 90. kJ/mol AH = kJ/mol
