    Negative Charge Stability: Oxygen vs. Carbon/Nitrogen

    I understand that, but my question was more along the lines of: Why is an sp2 hybrid C less able to stabilize the charge than nitrogen, but sp is better than nitrogen (I understand the principle that hybrid orbitals are closer to the nucleus and thus better able to stabilize -ve charge); at what...

    Negative Charge Stability: Oxygen vs. Carbon/Nitrogen

    You're right, I'm asking about a specific example from my organic chemistry textbook, but I didn't want to say that as I'm not asking for homework help; I'm just wondering why this is the case. As I understand it, these questions are here as examples of exceptions to the ARIO (atom, resonance...

    Negative Charge Stability: Oxygen vs. Carbon/Nitrogen

    Just to extend this idea, at what point does a hybrid carbon atom stabilize charge better than a more electronegative atom? For example, according to my textbook, an sp-hybrid C atom stabilizes negative charge better than a nitrogen atom. At what point does hybridization's effect overcome...

    Negative Charge Stability: Oxygen vs. Carbon/Nitrogen

    Why is it that it is more stable for a negative charge to be spread over 2 oxygens than one oxygen and 3 carbon atoms? Following that logic, why is it more stable to spread a negative charge over 3 oxygen atoms than over 1 oxygen atom and one nitrogen atom? Is it because the difference in...

    Equilibrium: Le Chatelier's Principle and CaCO3 Decomposition

    Homework Statement I had a question on a test and I got the wrong answer, but I still don't understand why. It was a Le Chatelier problem about the equilibrium shift, and it described the decomposition of CaCO3 CaCO3(s) <->CaO(s) + CO2(g) The question asked something along the lines of "If...

    Designing a Multimodal Learning Preference Test Using VARK Model

    Homework Statement For my data management class, I want to make a survey that has questions to test your learning preferences based on a VARK model (visual, aural, kinesthetic, and read/write) (I know the validity of the test itself is questionable, but I still think some interesting trends...

    Titration Troubles: Where Did We Go Wrong?

    Homework Statement We had a titration lab where we took 1.0 g of NaOH and added it to 50 mL of water. We then took that solution and added 10 mL of it to 500 mL of water, producing a 510 mL solution in total (this became the titrant). We then took 0.4 g of potassium hydrogen phthalate and...

    Why is the boiling point of 2-propanol lower than 1-propanol

    Homework Statement Why is the boiling point of 2-propanol lower than 1-propanol? The Attempt at a Solution Is this right? Because 2-propanol has its hydroxyl group in the middle of the atom, the electrons are all moving to the centre of the atom as opposed to 1-propanol, which has the...

    Methyl 2 hydroxybenzoate hydrogen bonding

    Homework Statement How many hydrogen bonds can methyl 2-hydroxybenzoate form with molecules of the same compind? Homework Equations N/A The Attempt at a Solution There's a hydroxyl group on the second carbon of the benzene ring and a double-bonded oxygen with 2(3?) lone pairs, so I'm...
