Why can't this product be major? And is double bond more nucleophilic than oxygen in this case?
In the following question: First the Cl will eliminate forming a double bond. After that the H+ attacks which has two possibilities, either the oxygen or the double bond. If it attacks the oxygen ...
Carbocation rearrangement with ring expansion
I was solving a particular question which landed me to a position where I have to decide whether the following ring expansion would take place or not by carbocation rearrangement: If the expansion ...
Comparing stability of 1,3-dioxolan-2-ide and 1,3-dithiolan-2-ide carbanions
I'd like to compare stability of 1,3-dioxolan-2-ide and 1,3-dithiolan-2-ide carbanions: I think there is no mesomeric or hyperconjugation effect and we should consider inductive effect. Oxygen is ...
major product formed in wurtz reaction in the given molecule[ 1,3-dibromo-2,2-di(1-bromomethyl)propane ]
This is the reactant molecule which undergoes wurtz reaction. All possible products are- What will be the most favorable in all of these? In my opinion that the last one should not be the one because ...
Why is C-S-C bond angle in thiirane so small at 48.5 degrees?
Why is the C-S-C bond angle in thiirane (48.5 degrees) so much smaller than C-O-C bond angle in oxirane/epoxide (60 degrees). Source: https://coek.info/pdf-three-membered-ring-heterocycles-.html
Mechanism of acid-catalyzed ring opening of a cyclopropane ring
I have a question regarding following synthesis which apparently only needs a sour medium to occur: What exactly happens as a mechanism? What I thought was: The alcohol group gets protonated and ...
Ring Flip of glucose
I have recently read about mutarotation of glucose specifically I am familiar with how cyclic structures like substituted cyclo-hexanes exist in an equilibrium of both their chair conformers. The ...
Stability of molecule based on ring size
During a discussion on chemically valid molecules based on atom valency, I was told that in molecules like $\qquad\qquad\qquad\qquad\qquad\qquad\qquad$ although the sum of the bonds that are incident ...
Comparing the stability of geminal diols [duplicate]
Arrange the given gemdiols in decreasing order of their stability: I thought that high angle strain would correspond to low stability, and therefore I compared the stability of the rings, which ...
