4:22 Dr Moore says that the first step is an oxidation at carbon 3. Is this a mistake? To my eyes, the oxidation would occur at carbon 2. This would induce the alpha carbon’s hydrogen to be acidic. This leads the way for elimination of a hydrogen and phosphate and formation of a double bond between carbons 3 and 4.

hello, I have a question. Do we have flow of electrons if we use voltage meter with very high resistance? i’m guessing with such high resistance there is no anode or cathode and we have an open circuit so there are no reactions occurring. if i’m wrong please correct me thank you

@mevansthechemist Ай бұрын

Voltage meters do use very little current, although the flow of a non-zero amount of charge is necessary to make the measurement. The voltage meter can only “sense” the higher-energy electrode when some charge moves. This does cause a voltage drop, but it’s a very tiny one that the meter can correct for. We use the terms “cathode” and “anode” generally to refer to the short-circuit or load situation, when the galvanic cell is acting as a battery to power something.

What level is needed to kill a plant? would one drop placed on a leaf kill the entire plant? Would accidentally spraying a small section of emerald arborvitae kill the tree?

The blocking of similar pathways, in people or plants! A wonderful example of how important this is! Particularly for Parkinson’s,and many similar diseases.

What if you would have a bifunctional initiator to induce anionic chain growth of bifunctional epoxides? Now the chain grows from 2 sides and can also connect to other growing chains, would this be considered as step growth?

My lecturer had an example of steric hindrance that could be overcome by a strong enough nucleophile. I thought it was because nucleophilicity had something to do with the thermodynamics and therefore the high energy scenario that steric hindrance is could be overcome if the nucleophile just made it thermodynamically favorable enough. If nucleophilicity is purely kinetics, that theory goes out the window. If you by chance had any time to enlighten me on the situation, I would of course be very grateful, but I understand if you dont have the time. (:

In case of ortho/para directors which one is major product

@mevansthechemist 2 ай бұрын

In most cases, as a rule, the para product dominates for steric reasons. There are exceptions involving directing-group effects or other subtleties, but as a rule, the para product forms in higher yield.

Hi Michael, can this LabQuest2 be used for the Vernier Melting Point apparatus? I was told that the Melting Point apparatus can work with any Vernier data acquisition.
