H_2O Why is BCl_3 nonpolar? Is the molecule BrCN polar or nonpolar? Explain. Is acetone polar or nonpolar? Explain. For the following compound, identify any polar bonds and determine if the structure is polar (explain why or why not). H_2CO Why are some covalent bonds polar and ...
Why trigonal planar is NonPolar? McCord - Trigonal Planar - 3 regions. If there are no lone pairs then the molecular geometry matches the electronic and is trigonal planar. ... POLARITY: NON-POLAR -As long as all three positions are the same, then the molecule cannot be polar due to per...
Which of the following has a zero dipole moment? a. CO b. SO2 c. SO3 d. NH3 Explain why CF_4 and KrF_4 are nonpolar compounds (have no net dipole moments), whereas SF_4 is polar (has a net dipole moment). Of the molecules below, only ___ has a dipole moment. a. SeF_4 ...
The lipophilic pathway is for nonpolar solutes that can enter the leaves through diffusion, while the hydrophilic pathway is for polar solutes [54]. Accordingly, NPs or their aggregates that are smaller than 4.8 nm in diameter can easily directly enter the cuticle through the cuticular pathway. ...
Why is O_2 nonpolar? What do water, carbon dioxide, and salt all have in common? Is CO_2 polar? What about COS? Explain. What is the difference between water soluble and organically soluble? Does CO2 or SO2 have a lower boiling point? Explain your reasoning. Explain why water is such...
Describe the health consequences of CO poisoning. What are the possible treatments? Explain why the following compound is not aromatic. Why is carbon 14 less stable than carbon 12? Why toxicological chemistry is a significant part of environmental chemistry? Why is O_2 nonpolar? Why are active ...
Why p-bromobenzylchloride (″S″S) is positive, while p-nitrobenzylchloride (″S″S) is negative? Dextro and Levorotatary Isomers: This isomerism is shown by the incident light's polarization based on a certain plane that holds either + or - orientation. This isomerism ...
Why is CO a stronger ligand than Cl-? Why NH4+ ion is not strong ligand? Why can NH3 function as a ligand with Ni2+ while NH4+ cannot function as a ligand with Ni2+? Explain the term ligand as used in chemistry. Why are anions always larger than the atoms from which they a...
Al(OH)3 Describe the following as being a Bronsted acid, base, or both: a) H2CO3 b) HCO3-1 c) CO3-2 Give an example of a conjugate pair in which neither species is either a strong acid or base. (Identify the acid and the base....
For the moleculeHOFO, why is the lewis structure all single bonds? Lewis Structure: Two atoms form one or more covalent bonds by sharing the same number of valence electron pairs. The goal of this bonding is to achieve a stable noble gas electron configuration for each participating ...
