I need help with this homework. I've been sick and out of class and don't know how to do it!! :(

... wm ve Serected at random for grading, but a full answer key will be posted to Blackboard. 1. Below is a nanodragster. YES, we can make machines-cars, even at the nano-scale, the sizes of molecules. This little nanodragster has some nifty features. Its chassis is rigid like the chassis of a real car. The main axis of the nanochassis, which is boxed below, is held together by sigma bonds. It's also rigid like a real chassis, but the rigidity comes from pi bonds. OCM21 OCH HH₂, C,00 H21C,00 H21C0g Hoc, ot21 Coffocatori How many pi bonds are shown within the box? On the boxed portion of the molecule, there are several sp-hybridized carbon atoms. On the image above, point to these carbon atoms using arrows. Count the number of sp-hybridized carbons within the box:
This nanodragster is a bit sluggish, though, and requires higher temperatures to get it to go. It was clocked at 0.0006 in /hr. What is this speed in nm/s? In the future, they hope to design better nanocars that move faster and haul payloads of small molecules around. cartoon Constructed image from actual data * 19 2. Nanocars are raced in organic solvents. (Yes, raced! There was a nanocar race in France a couple years back.) Below are some organic solvents that could be used. Provide a list of intermolecular forces each organic molecule below could participate in. CI: 09 Η C HC CH C H CN |c CI: HH
3. Cyantriniliprole is an insecticide-a member of a whole family of insecticides called ryanoids (We have a dearth of Ryans in the class this semester, so maybe this helps cover our Ryan deficit.) The structure of cyantriniliprole is shown below, and some of the bonds are numbered. Order these from left to right, from shortest chemical bond to longest chemical bond. Number sequence: I'd like you to understand chemical information the same way you may encounter it in your career. The structure above was taken directly from Wikipedia. Fill in the missing lone pairs! How many carbon atoms are implicit in this chemical structure? Say that two bonds are different lengths, and hence, different strengths. Draw curves on the diagram below that shows their bond energy curves. Remember that the position of the minimum along the X axis indicates the average bond length. The depth of the curve represents the bond strength. Your curves only need to show these features correctly relative to one another. You do NOT need to label axes and draw curves accurately and to scale. Energy RAB / bond length

5. Below is the same set of molecules as problem 2. Identify both the electron group geometry and the molecular geometry around atom b. Then identify the bond angle labeled e-b-c in each molecule Predict if it will be greater than, less than or equal to your value, based on electron-electron repulsion Electron group geometry around atom b Electron group geometry around atom b Electron group geometry around atomb Electron group geometry around atomb molecular geometry around atom b molecular geometry around atom b molecular geometry around atom b molecular geometry around atom b bond angle a-b-c bond angle o-b-c bond angle o-b-c bond angle o-bo
6. Like the picture we started sketching in class for CO2, Sketch a picture of the bonding in water, H2O. may help to draw the Lewis structure first. Make sure to label the orbitals whether atomic or hybridized 7. Also sketch a picture of the bonding in formaldehyde, CH20. It may help to draw the Lewis structure first. Make sure to label the orbitals whether atomic or hybridized.
