Answer to Problem 108AE
The enthalpy of formation of
Explanation of Solution
Nitrogen trifloride is colorless, inorganic thermally stable compound. It is non- flammable in nature. The stability is due to comparable size of nitrogen and fluoride. While the nitrogen iodide is an explosive compound due to the difference in the size of the atoms.
Consider the following reaction
Consider the enthalpy of formation of
Subtitling
Thus, the enthalpy of formation of
(b)
Interpretation : The molecular geometries of the species are determined.
Concept Introduction :
The molecular geometry is the three dimensional shape of the atom that contains the molecule. It consists of the general shape which contains bond lengths, bond angles, transition angles and other parameters determining the position of atoms.
(b)

Answer to Problem 108AE
It will have 4 bond pairs and the geometry will become tetrahedral with
Explanation of Solution
According to the vesper theory the molecular geometry are predicted as follows
Total valance shell electrons of the
Thus it will have 2 lone pairs and 2 bond pairs and the geometry will become V-shaped geometry with
It is represented as follows:
Total valance shell electrons of the
Thus it will have 4 bond pairs and the geometry will become tetrahedral with

- For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. དྲ。 ✗MgBr ?

NH2 tu ? ? OH Will the first product that forms in this reaction create a new CC bond? Yes No Will the first product that forms in this reaction create a new CC bond? Yes No C $ ©arrow_forwardAs the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C-C bond as its major product: 1. MgCl ? 2. H₂O* If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. This reaction will not make a product with a new CC bond. G marrow_forwardIncluding activity coefficients, find [Hg22+] in saturated Hg2Br2 in 0.00100 M NH4 Ksp Hg2Br2 = 5.6×10-23.arrow_forward
