Torsional Strain

What aspect of bonding determines torsional strain? What does torsional strain mean for a molecule's potential energy?

Re: Anion Stability

Anion stability is necessarily affected by carbon string length. CH3COOH has better anion stability than C3H7COOH because CH3COOH is has more electronegative atoms next to the charge (the COOH being right next to the anion). More electronegative atoms next to the charge results in more stability.

Re: Alkyl and Aryl Carbanions

Aryl carbanions are aromatic compounds (part of carbons having sigma bonds and delocalized pi bonds forming a ring) and have a -1 charge whereas Alkyl carbanions are non aromatic compounds and have a +1 charge.

Re: Double bond of an alkene

In this case, (An Alkane which is a hydrocarbon with a double bond, is involved) the double bond electrons always act as the nucleophiles because otherwise the alkane would be broken into two molecules. In other cases, single bonds can possibly act as nucleophiles if the decomposition of the molecul...

Re: activation energy

The A value or pre-exponential factor would be given to you in this case if you are trying to find the activation energy. It would also be the y-intercept in a graph of lnk vs 1/T.

Re: Oxidation and Reduction

Hello. In regards to the second part of your question, a positive E value denotes a reduction whereas a negative E value denotes oxidation.

Re: 2 Half Reactions

Reversing the half reaction with the larger E would result in the full reaction having a negative cell potential. If a reaction has a negative cell potential, it will not be spontaneous and therefore not occur naturally.

Re: Sign of Gibbs Free Energy

The reaction is spontaneous at high temperatures when both enthalpy and entropy are positive because a high temperature will cause the positive entropy to dominate over the positive enthalpy. This results in a negative delta G, meaning that free energy was used to do work and thus the reaction has o...

Re: Changes in Volume

Yes, volume change is negligible when solids and liquids are involved in a reaction within a closed or isolated system. When a gas substance undergoes a physical change into either a solid or liquid, the change in volume is incredibly high compared to when a solid or liquid changes into a liquid or ...

Re: Vaporization Heat Transfer

Vaporization is an endothermic reaction as energy is being put into a system in order to convert a liquid substance to a into gas. Endothermic reaction always involve the input of energy to break chemical bonds
