Steric Repulsion - Simple Explanation? - Physics Forums
2016年8月26日 · Steric repulsion, also known as steric hindrance, is a phenomenon in chemistry where the spatial arrangement of atoms or groups of atoms around a central atom creates a repulsive force between them. This repulsive force prevents them from coming too close to each other and affects the reactivity and physical properties of a molecule.
What is the Effect of Ferrofluid Surfactant on Particle Repulsion?
2012年6月30日 · Steric repulsion is an important consideration in drug design and development because it can affect the binding of a drug molecule to its target receptor. If the drug molecule is too large and has too many steric interactions, it may not fit into the receptor properly and therefore be less effective.
Conformation Stability of Ethane-1,2-Diol - Physics Forums
2022年7月24日 · This is what makes it more stable overall.In summary, the conversation discusses the concept of torsional strain and how it is affected by the presence of hydrogen bonding in alcohol groups. It is explained that the hydrogen bonding helps to overcome the steric repulsion in the gauche conformation, making it more stable than the anti conformation.
Why do some elements in column 14 have different shapes than …
2004年2月18日 · This is actually a very good question, and one that has garnered a lot of attention from researchers. The quick answer would be to say that VSEPR only applies to electron PAIR repulsion, and not unpaired electrons. But the fact is that, while the CH 3 ⋅ radical is planar, other alkyl radicals are pyramidal (most notably CF 3 ⋅). There are a ...
Understanding the Properties of Water at 104.45° - Physics Forums
2007年10月24日 · In summary, the angle of water being 104.45° is due to the sp3 hybridization of the O-atom and the greater repulsion from non-bonding electron pairs. However, there is now evidence to suggest that the 2s orbital is unhybridized and the angle is further affected by steric repulsion from the hydrogen atoms.
Organic Chemistry stable conformation question - Physics Forums
2009年8月29日 · Since O is in the plane of the ring and all equatorial bonds are in the plane of the ring.So we can also say that when Br on second carbon is axial ,it minimizes steric repulsion .More suitable situation and favorable also.If you see this explanation again takes you on the first which we discussed on the basis of LP-Lp.What is steric repulsion ...
Understanding Bulky Groups: Definition and Explanation - Physics …
2010年9月23日 · In summary, the term "bulky group" refers to a group in a molecule that is large and has steric hindrance, meaning that it affects the reactions that can take place. Examples of bulky groups include t-butyl and non-bulky groups include cyanide and azide ions. It may be helpful to use a model set to visualize the size and shape of these groups.
Why isn't ClF3 trigonal planar? - Physics Forums
2018年7月4日 · The molecular geometry of ClF3 is primarily determined by the steric number, which is influenced by the number of regions of electron density around the central atom. Additionally, the presence of lone pairs and the repulsion between them also impact the molecular geometry. 4. Is ClF3 a polar molecule?
Which Cyclohexane-1,2- or 1,3-Diol Isomer is Most Stable?
2018年9月6日 · Steric hindrance refers to the repulsion between atoms or groups, while electronic effects refer to the influence of electron distribution on the stability of the molecule. Conformational energy is the energy required to change the shape of a molecule.
Memorizing VSEPR Structures: A Simple Method for Success
2014年11月13日 · Steric number 6 = 3 structures. Last one kind of breaks the rule but I still find this helps. 2. Now you have to memorize the structures in each steric number group. Steric number 2 = Linear (180 degrees) Steric number 3 = Bent and Trigonal Planar (Both 120 degrees) Steric number 4 = Tetrahedral, Trigonal Bipyramidal and Bent again.
