Three-dimensional bond-line structures | Structure and bonding | Organic chemistry | Khan Academy

– [Voiceover] In the video on bond line structures, we started with this Lewis dot structure on the left, and I showed you how to turn this Lewis dot structure into a bond line structure. So here’s the bond line structure that we drew in that video. Bond line structures contain the same information as […]

Formation of nitrate esters | Organic chemistry | Khan Academy

Here’s the general reaction to form nitrate esters from alcohol. So we have our alcohol over here on the left. And we react that with some concentrated nitric acid and concentrated sulfuric acid as our catalyst. And I believe this reaction is reversible. So we could think about that. We would form our nitrate ester […]

Introduction to proton NMR | Spectroscopy | Organic chemistry | Khan Academy

– The nucleus of a Hydrogen atom is a proton and has a property called spin. So you can think about, just as a visual aid, you can think about this proton that’s spinning this way. A spinning proton, right, is like a rotating sphere of charge, and any moving charge creates a magnetic field. […]

Chemical Earmuffs: The Future of Hearing Protection? | SciShow News

[INTRO ♫] Everywhere from construction jobs to rock concerts, loud noise carries a risk of permanent damage to your hearing. But a new study published this week in the journal PNAS has found a chemical trick that might help block the harmful effects of noise on our ears. They developed a drug-based procedure that actually […]

General Chemistry Review for Organic Chemistry Part 3

Welcome to part three of the general chemistry review for organic chemistry. I’m Melissa Maribel your personal tutor and let’s go over formal charges. Formal charges are the charges of each individual atom within the molecule all the formal charges add up to the overall charge of the molecule. Formal charges are a great way […]

Chair and boat shapes for cyclohexane | Organic chemistry | Khan Academy

For all the cyclic molecules we’ve dealt with so far, we’ve just drawn them as rings. For example, for cyclohexane we’ve literally just drawn it as a hexagon. So we’ve drawn cyclohexane like that. Now, we know from the last several videos that all the bonds for carbon don’t sit in the same plane. If […]
