- How many valence electrons does a neutral a. K atom have? b. C atom? N atom? O atom?arrow_forwardWhy is it less clear to see the electrons on HBrO2 molecular electron geometry than it is on something like H2O? I know there should be 20 electrons on HBrO2, but this leads me to an incorrect drawing. And with the correct drawing, I don't see where all the electrons are. It seems like there's only 10 total. What am I missing here?arrow_forwardA model for NH3 is shown in the chem3D window. NH3 has trigonal pyramidal geometry. ball & stick v-+| labels Rotate the molecule until you have a feeling for its three-dimensional shape. How many atoms are bonded to the central atom? If you consider only the three outer atoms, what shape do they define?| Consider the bond angles at the central atom. Do they all have approximately the same numerical value? What is the approximate numerical value of this angle? degrees. Does the central atom lie in the plane defined by the three other atoms? Are all three positions about the central atom equivalent, or is one of them different from the other two. For practice, type in the name of the geometry of the molecule:arrow_forward
- Arrange the following molecules in order of decreasing polarity of their bonds. Rank the elements from strongest to weakest. To rank items as equivalent, overlap them. Strongest PBr3 The correct ranking cannot be determined BH3 SeF₁ H₂O Reset Help Weakest Arrange the following molecules order of decreasing polarity of their bonds. Rank the elements from strongest to weakest. To rank items as equivalent, overlap them. Strongest PBr ВН, SeF, H₂O The correct ranking cannot be determined Reset Help Weakestarrow_forwardWhich of the highlighted chemical bonds in the molecules below is longest? Shortest? In between? Which highlighted bond requires the highest energy to break? Lowest? In between? Answer these questions by completing the second and third columns in the table. compound H HICIO | H :C=0: :0: || H-C-H H length of highlighted bond choose one choose one - V choose one - ✓ energy of highlighted bond choose one choose one choose one X Śarrow_forwardIn the actual molecule of which this is a Lewis structure, which of the labeled distances can change? marked unmarked H A B You can click the "unmarked" tab to see the molecule without any of the distances marked. H H. List all the distances that can change. For example, suppose all the distances were measured at a certain time, and again 0.1s later. If distance A might be 50% bigger or smaller the second time, but all the other distances are certain to be the same, you should write "A". If A and B might be different the second time, but no other distances, you would write "A, B". And so on. Note for advanced students: you can assume the molecule is dissolved in an appropriate solvent at room temperature. OO,... ?arrow_forward
- For each compound in the table below, decide whether there would be any hydrogen-bonding force between molecules of the compound, or between molecules of the compound and molecules of water. name dimethyl ether iodomethane acetic acid compound formula or Lewis structure H T H-C-Ö-C-H I H HILIA CH₂I | H H :O: | || H-C-C-O-H Between molecules of the compound?

Its formula is: CH3CH2CHCHCH2CH2OCHCH2CH3 | OCH3 Please draw a Lewis structure for this compound with CORRECT GEOMETRY (use dashes and wedges!) Label all pi bonds in the molecule (if there are any) Indicate the bond angles for the red highlighted section of the molecule. (hint: you may want to keep the main carbon chain in-plane with the page for clarity) For this question, you don’t need to draw out the orbitals.arrow_forwardis there any line structure explanation of this?arrow_forward
- Please fill in the blank ! In part B, the difference is that the molecules have more than one atom with two or more attached neighbors. As molecules become larger and more complex, VSEPR theory does not attempt to create names for the overall geometries that result. Instead, we continue to consider the geometry about one central atom at a time. By giving the arrangement about each such atom in the larger structure, we can generate enough information to develop an overall picture. Thus, in your report for part B, you should determine which atoms have more than one bound neighbor, then repeat the procedure for part A. When deciding whether the molecules in part B are polar or nonpolar, focus on the molecule as a whole, not the geometry about a single atom. If the molecule is polar, draw a dipole arrow on your sketch indicating polarity.arrow_forwardFocus on the C atom on the left as the central atom. How many other atoms are directly bonded to this C atom? How many bonding domains are there on the C atom on the left? How many lone pairs of electrons are there on the C atom on the left? How many nonbonding domains are there on the C atom on the left?arrow_forwardWhat is the total number of sp2 hybridized carbon atoms present in this molecule? What is the total number of sp3 hybridized carbon atoms present in this molecule? What is the total number of methyl groups present in this molecule?arrow_forward
