Concept explainers
(a)
Interpretation:
Whether the N2 molecule is polar or nonpolar needs to be identified.
Concept Introduction:
The atoms present in a molecule having large difference in their electronegativity results in polar nature of the molecule.
If the difference in electronegativity is lower or approching to 0 then the molecule will be non-polar in nature.
The range of non-polar bond is 0 to 0.4 while for polar covalent bond the range is 0.4 to 1.8 and for ionic bond the range is 1.8 to 3.3.
(b)
Interpretation:
Whether the TeO2 molecule is polar or nonpolar needs to be identified.
Concept Introduction:
The atoms present in a molecule having large difference in their electronegativity results in polar nature of the molecule.
If the difference in electronegativity is lower or approaching to 0 then the molecule will be non-polar in nature.
The range of non-polar bond is 0 to 0.4 while for polar covalent bond the range is 0.4 to 1.8 and for ionic bond the range is 1.8 to 3.3.
(c)
Interpretation:
Interpret whether NH2Cl is polar or nonpolar molecule.
Concept Introduction:
The atoms present in a molecule having large difference in their electronegativity results in polar nature of the molecule.
If the difference in electronegativity is lower or approaching to 0 then the molecule will be non-polar in nature.
The range of non-polar bond is 0 to 0.4 while for polar covalent bond the range is 0.4 to 1.8 and for ionic bond the range is 1.8 to 3.3.

- 3. Use Kapustinskii's equation and data from Table 4.10 in your textbook to calculate lattice energies of Cu(OH)2 and CuCO3 (4 points)arrow_forward2. Copper (II) oxide crystalizes in monoclinic unit cell (included below; blue spheres 2+ represent Cu²+, red - O²-). Use Kapustinski's equation (4.5) to calculate lattice energy for CuO. You will need some data from Resource section of your textbook (p.901). (4 points) CuOarrow_forwardWhat is the IUPAC name of the following compound? OH (2S, 4R)-4-chloropentan-2-ol O (2R, 4R)-4-chloropentan-2-ol O (2R, 4S)-4-chloropentan-2-ol O(2S, 4S)-4-chloropentan-2-olarrow_forward
- Use the reaction coordinate diagram to answer the below questions. Type your answers into the answer box for each question. (Watch your spelling) Energy A B C D Reaction coordinate E A) Is the reaction step going from D to F endothermic or exothermic? A F G B) Does point D represent a reactant, product, intermediate or transition state? A/ C) Which step (step 1 or step 2) is the rate determining step? Aarrow_forward1. Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference.
