Ortho - hydroxyacetophenone vs para - hydroxyacetophenone polarity?
para is more polar than the ortho
What is ortho meta and para in benzene?
ortho-para in benzene is meaningless these positions are for monosubstituted benzene. Meta is positions 3 and 5. Ortho is position 2 and 6 with relation to already attached group, para is 4 (opposite) to attached group.
Why halogens that is deactivate group attack to ortho and para position?
Because of mesomeric effect, the electron density on the ortho and para positions for the aromatic ring is more.
Activating and deactivating group of Ortho para and meta director groups Explain?
You can either deactivate or activate the group of Ortho para and Meta director groups depending with your preference.
Why nitroso in nitrosobenzene deactivating yet ortho para directing?
NO-group acts exactly as halogens because of long pair on nitrogen. This pair stabilizes ortho-para intermediates.
Ortho - hydroxyacetophenone vs para - hydroxyacetophenone polarity?
para is more polar than the ortho
How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.
Why methyl attached to benzene is ortho-para director group?
This group attached to benzene ring acts as the ortho-para directing group due to Hyperconjugation.
What is ortho meta and para in benzene?
ortho-para in benzene is meaningless these positions are for monosubstituted benzene. Meta is positions 3 and 5. Ortho is position 2 and 6 with relation to already attached group, para is 4 (opposite) to attached group.
How do you separate ortho and para nitro phenol?
by steam distillation as o-nitrophenol is volatile due to intra-molecular hydrogen bonding, SYNCRO, GKP
Why halogens that is deactivate group attack to ortho and para position?
Because of mesomeric effect, the electron density on the ortho and para positions for the aromatic ring is more.
What are the examples of Ortho and para directing group and mata directing group?
Electrophilic Aromatic Substitution is an example of Ortho and para directing group and meta directing group.
What is the ortho-peradirective nature?
I think you're asking about ortho-para directors. o,p directors are groups bonded to a benzene ring that direct additional groups in electrophilic aromatic substitution reactions to attach to the ortho and para positions of the benzene ring. Ortho is the position next to the group and para is the position across from the group on the benzene ring. o,p directors are electron donating groups such as methoxy groups. These groups stabilize the positive charge created in the intermediate when the electrophile adds to the ortho and para positions. o,p directors do not, however, stabilize the positive charge when the electrophile adds to the meta position and therefore only allow addition to the ortho and para positions (thus the name ortho-para director).
Activating and deactivating group of Ortho para and meta director groups Explain?
You can either deactivate or activate the group of Ortho para and Meta director groups depending with your preference.
Why nitroso in nitrosobenzene deactivating yet ortho para directing?
NO-group acts exactly as halogens because of long pair on nitrogen. This pair stabilizes ortho-para intermediates.
What are the differences between ortho hydrogen and para hydrogen?
Positioning around a benzene ring relative to the major functional group. Para is opposite, ortho is next to, meta is in between.
What is para and ortho hydrogen?
A molecule of diatomic hydrogen (hydrogen gas) contains two hydrogen atoms. The nucleus of each aton (a protron) is spinning. Depending upon the direction of the spin of the two nuclei, the hydrogens are of two types: ortho or para. Ortho-hydrogen molecules are those in which the spins of both the nuclei are in the same direction. Para-hydrogen is when the spins of both the nuclei are in the opposite directions. Ordinary hydrogen gas is an equilibrium mixture of ortho and para hydrogen. The amount of ortho- and para-hydrogen varies with temperature. At 0°K, hydrogen contains mainly para-hydrogen which is more stable. At the temperature of liquid of air, the ratio of ortho- and para-hydrogen is 1 : 1. At the room temperature, the ratio of ortho- to para-hydrogen is at its maximum of 3 : 1. Even at very high temperatures, the ratio of ortho- to para-hydrogen can never be more than 3 : 1. So, it is possible to get pure para hydrogen by cooling ordinary hydrogen gas to a very low temperature (close to 20 K) but it is never possible to get a sample of hydrogen containing more than 75% of ortho hydrogen.
