Concept explainers
Interpretation:
The Lewis structure for Tetrachloraluminate ion and the type of bond for its formation has to be drawn.
Concept Introduction:
Octet Rule:
The octet rule states that the noble gas electron configuration is attained by the element, when the element either loses or gains or shares its atoms. The formulas for the compounds that contain specific elements can be predicted with the help of Octet rule. The octet rule holds good for those compounds that are made of elements present in second period and hence the important study on organic compounds that mainly consists of Carbon, Nitrogen and Oxygen atoms can be done with the help of Octet rule. The loss gain or sharing electrons of particular atom is dependent on properties of atoms that are determined by the number of subatomic particles inside in the atom.
Lewis structure:
The Lewis structure otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.

- Which molecule has the most polar bond: N2, BrF, or ClF? Use an arrow to show the direction of polarity in each bond.arrow_forwardBond Enthalpy When atoms of the hypothetical element X are placed together, they rapidly undergo reaction to form the X2 molecule: X(g)+X(g)X2(g) a Would you predict that this reaction is exothermic or endothermic? Explain. b Is the bond enthalpy of X2 a positive or a negative quantity? Why? c Suppose H for the reaction is 500 kJ/mol. Estimate the bond enthalpy of the X2 molecule. d Another hypothetical molecular compound, Y2(g), has a bond enthalpy of 750 kJ/mol, and the molecular compound XY(g) has a bond enthalpy of 1500 kJ/mol. Using bond enthalpy information, calculate H for the following reaction. X2(g)+Y2(g)2XY(g) e Given the following information, as well as the information previously presented, predict whether or not the hypothetical ionic compound AX is likely to form. In this compound, A forms the A+ cation, and X forms the X anion. Be sure to justify your answer. Reaction: A(g)+12X2(g)AX(s)The first ionization energy of A(g) is 400 kJ/mol. The electron affinity of X(g) is 525 kJ/mol.

- An important observation supporting the concept of resonance in the localized electron model was that there are only three different structures of dichlorobenzene (C6H4C10). How does this fact support the concept of resonance (see Exercise 89)?arrow_forwardExplain why bonds occur at specific average bond distances instead of the atoms approaching each other infinitely close.arrow_forwardWhich bond requires more energy to break: the carbon-oxygen bond in formaldehyde, H2CO, or the carbon-oxygen bond in carbon monoxide, CO?arrow_forward
