AI Thread Summary
Determining the priority for substituents around a chiral center involves comparing the atomic numbers of the atoms directly attached to the chiral carbon. Hydroxyl groups (-OH) have the highest priority due to the oxygen atom's higher atomic number compared to hydrogen. When two substituents are identical, such as two -OH groups, their priority is equal. In cases where one substituent has a carbon atom attached, that substituent ranks higher than those with only hydrogen atoms. Understanding these rules is essential for accurately assigning priorities in chiral centers.

The Attempt at a Solution



My issue here is the priority, I know OH has the greatest priority, and H the least, but I really cannot figure out the priority of the other 2 bonded to the carbon... ??

1) both have an -OH, equal; 2) one has another C which outranks the pair of H.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
