hyperconjugation sentence in Hindi
Sentences

- The hyperconjugation between out-of-plane ? bonds is greater because the in-plane ? bonds are poorly aligned.
- Hyperconjugation can also explain several other phenomena whose explanations may also not be as intuitive as that for the rotational barrier of ethane.
- An analysis within quantitative molecular orbital theory shows that 2-orbital-4-electron ( steric ) repulsions are dominant over hyperconjugation.
- The existence of specific conformations is due to hindered rotation around sigma bonds, although a role for hyperconjugation is proposed by a competing theory.
- Both the hyperconjugation and the dipole minimization contribute to the preferred ( Z )-conformation of esters over the ( E )-conformation.
- This orientation allows for hyperconjugation of O-5 to O-4 and O-6, removing electron density from O-5.
- Hyperconjugation model for explaining the gauche effect in 1, 2-difluoroethaneThere are two main explanations for the gauche effect : hyperconjugation and bent bonds.
- Hyperconjugation model for explaining the gauche effect in 1, 2-difluoroethaneThere are two main explanations for the gauche effect : hyperconjugation and bent bonds.
- A well-studied example of delocalization that does not involve ? electrons ( hyperconjugation ) can be observed in the non-classical 2-Norbornyl cation.
- On the other hand, an analysis within quantitative molecular orbital theory shows that 2-orbital-4-electron ( steric ) repulsions are dominant over hyperconjugation.
- This maximum is often explained by steric hindrance, but its origins sometimes actually lie in hyperconjugation ( as when the eclipsing interaction is of two hydrogen atoms ).
- The ? anomer is the major conformer, although somewhat controversially; this is due to the anomeric effect with the stabilisation energy provided by n-? * hyperconjugation.
- This type of bond also occurs in carbon compounds, where it is sometimes referred to as hyperconjugation; another name for asymmetrical three-center two-electron bonds.
- Goodman also conducted studies to determine the contribution of vicinal ( between two methyl groups ) vs . geminal ( between the atoms in a single methyl group ) interactions to hyperconjugation.
- I can accept that deprotonation ( of an alcohol ) is generally faster than SN2 . . . and maybe the chloro group makes the alcohol more acidic ( by inductance and hyperconjugation ).
- Hyperconjugation, which describes the stabilizing interaction between the HOMO of the alkyl group and the LUMO of the double bond, also helps explain the influence of alkyl substitutions on the stability of alkenes.
- In the hyperconjugation model, the donation of electron density from the C H ? bonding orbital to the C F ? * antibonding orbital is considered the source of stabilization in the gauche isomer.
- Negative hyperconjugation is most commonly observed when the ? *-orbital is located on certain C F or C O bonds, and does not occur to an appreciable extent with normal C H bonds.
- One common criticism of the hyperconjugation theory is that it fails to explain why the anomeric effect is not observed when substituted tetrahydropyran molecules are placed in polar solvents, and the equatorial position is once again preferred.
- An example is the Friedel Crafts alkylation of benzene with 1-chloro-2-methylpropane; the carbocation rearranges to a " tert "-butyl group stabilized by hyperconjugation, a particular form of delocalization.
