In ionic bonds, the electrons in the bond are actually donated to one atom by the other (e.g., NaCl). Ionic bonds form between atoms when the electronegativity difference between them is more significant than 1.7. Technically ionic bonds are simply polar bonds so that the terminology can be...
Describe the difference between ionic and covalent bonds. Specify whether CH4 is polar, nonpolar, ionic, or polar covalent. Is the P-P bond ionic, polar covalent, or nonpolar covalent? Explain. Classify the F-O bond as nonpolar covalent, polar covalent, or ionic. ...
Which of the following molecule has a polar bonds but is non-polar? a. XeF2 b. N2 c. CIF3 d. H2O Which of the following bonds is least polar? H3/4B H3/4N H3/4C H3/4O H3/4F Identify the most polar bond in each molecule. (a) HSCH2CH2OH (b) CHCl2F (c) HOCH2CH2NH2 Which...
2. Would B(CH3)3 (Lewis acid) + OH- form (CH3)2B-O and CH4? 3. Would protonized Imidazole (C3H3N2H2+(?)) have more than 3 resonance forms? 4. Why would CH3F have a smaller dipole moment than CH3Cl if Fluorine is more electronegative? 5. Is the O-H hydrogen in ethanoic ac...
How do polar molecules form hydrogen bonds? Which bond is the most polar: C-H, O-H, N-H, F-H? Is carbon disulfide polar? What does electronegativity have to do with polarity? a) Are there polar bonds in water? (Show EN for each of the bonds in the molecule) b) What is the ...
9-8 Hybridization When chemists measure the bond lengths and strengths of the 4 C – H bonds in CH4, the bonds are equivalent in both length and strength. The question is: “How could four equivalent bonds form when the four valence electrons in the carbon atom are arranged with 2 in ...
For example, for the CH2 group z = 0.36 and the inductive effect, which propagates over the C—C bonds, in the γ-position is proportional to 0.363 = 0.046, i.e., lower than 5%. The fast decay of the inductive effect is associated with the weak polarizability of orbitals of σ-...
The absolute values of the electronegativity differences between the atoms in the bonds HH, HCl, and NaCl are 0 (nonpolar), 0.9 (polar covalent), and 2.1 (ionic), respectively. If the difference is greater than 2, then the bond is completely polar, and is more properly referred to as an...
N-pentane is nonpolar. N-pentane is a hydrocarbon composed of only carbon and hydrogen atoms. Like any simple hydrocarbon only composed of C-H bonds,...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer ...
