Over the past week, we finished our test from last week about the basic structures of molecule. Now we transitioned into basically the intramolecular and intermolecular bond in molecules. Since football season is finally over, I can finally go home after school and get some rest. On Monday, I joined a new club that my friend made which was the "rock climbing" club. It was really fun, we had pizza, we climbed and got really sore afterwards. Last weekends, I remembered we were assigned with two moodle quizzes online about the basic inter- and intramolecular forces.
We did lots of lecture quizzes online and they were really easy. Intramolecular forces are forces that keeps the bond together within a molecule. Whereas internmolcular forces are forces between molecules. We went over lots of pogils in class throughout the week. We discover basically the trend of boiling points of molecules comparing to its molecular size/ charges. We also went over the different kinds of LDFs (London Dispersion Forces) within a molecule. Hydrogen bonds can only happen between hyrdrogen and nitrogen, oxygen, fluorine, also known as, NOF. Out of all the LDFs, hydrogen bond is the strongest out of all. Then it moves on to dipole induced to dipole-dipole. Its pretty simple. In simple words, the bigger the size of the molecule, the higher the boiling point. Then, the information is not provided, then we compared the charges of the molecule to see how polarizable the molecule is.
It all makes sense, if the molecule has a closer together due to its stronger intramolecular force then it would take more energy to dissolve it in water, so higher boiling point. Then over the weekend, we were assigned with a lecture quiz about solids and liquids. It shows basically the intremolecular forces difference between the different kinds of solids, which were molecular solids, covalent network solids, ionic solids and metallic solids. We also went over the viscosity of molecules. The more viscous a molecule is, the thicker it is, the harder it is to boil. I still can't believe the trimester is almost over. Time really flies by, in a blink of an eye and my high school is almost over. One more year, then I am pretty much done. I am really stressed now about all the standardized tests, college, and my grades. My grades are very "disappointing" right now. I am trying to do my best to bring them up. I am now very determined to get all A's next trimester. Also, I am interested in joining the research program that Dr. F sent to us. It's pretty cool though, to live in a college campus over the summer and just study science the whole day. Lastly, I dissected a cow eye on Friday which was pretty excited. It was interesting to see the different structures of our eye. It really is amazing how our body works.
