What are the differences between activating and deactivating groups in electrophillic aromatic substitution?
Activating groups donate electron density either through inductive effects or resonance. They are usually ortho and para directed, which means the subsequent groups added will either be in the 2 or 4 position relative to the functional group.
It is easy to determine if a functional group is activating if it electronegative molecules are single bonded.
Examples: alkyl groups (-CH3), alkoxyl (-OCH3), amino (-NH2), thio (-SH),
The exception to the trend that activating groups = ortho/para are halides. Halides are deactivating groups because of strong electronegativity, but they are also ortho and para.
Molecules that are double bonded like -NO2, HSO4, and halides are deactivating. They are meta directed, adding molecules at the 3 position.

What makes a substituent activating?
A substituent is considered activating when it donates electrons to the benzene ring, which increases the electron density of the ring and enhances its reactivity towards electrophilic aromatic substitution reactions. Common activating substituents include -OH, -NH2, and -CH3 groups.
What is part of the midbrain?
Reticular Activating System
Are proteins regulators of cell division?
Yes, proteins play a crucial role in regulating cell division. Proteins such as cyclins and cyclin-dependent kinases (CDKs) form complexes that control the progression of the cell cycle by activating or deactivating various checkpoints. These proteins regulate key events like DNA replication and chromosome segregation to ensure proper cell division.
Stimulation of the reticular activating system makes us?
more alert and awake by regulating our level of consciousness and attention. The reticular activating system is responsible for filtering sensory information and sending signals to the brain to promote wakefulness and vigilance.
Where does the Reticular Activating System (RAS) originate?
The temporal lobe is responsible for controlling:
What is activating and deactivating a mobile phone?
yes
Is the SO3H group activating or deactivating in the given reaction?
In the given reaction, the SO3H group is activating.
Is a methyl group activating or deactivating in the context of organic chemistry?
In organic chemistry, a methyl group is typically considered activating, meaning it increases the reactivity of a molecule.
Activating and deactivating group of Ortho para and meta director groups Explain?
Ortho, para, and meta-directing groups are electron-donating or electron-withdrawing substituents in aromatic compounds. Activating groups increase the electron density on the ring, making it more reactive towards electrophilic substitution. Deactivating groups reduce the electron density on the ring, making it less reactive. The specific positions favored for substitution (ortho, para, or meta) depend on the nature of the substituent and its effects on the ring.
What layer of the OSI Model defines the electrical mechanical procedural and functional specifications for activating maintaining and deactivating the physical link between communicating net?
Physical
What makes a substituent activating?
A substituent is considered activating when it donates electrons to the benzene ring, which increases the electron density of the ring and enhances its reactivity towards electrophilic aromatic substitution reactions. Common activating substituents include -OH, -NH2, and -CH3 groups.
What are the differences in the functions and mechanisms of action between kinase, phosphatase, and phosphorylase enzymes in cellular signaling pathways?
Kinases add phosphate groups to proteins, activating them in cellular signaling pathways. Phosphatases remove phosphate groups, deactivating proteins. Phosphorylases break down glycogen into glucose for energy. These enzymes play key roles in regulating cellular processes through their actions on protein phosphorylation.
What are the key differences between kinase, phosphorylase, and phosphatase in terms of their roles in cellular signaling pathways?
Kinases are enzymes that add phosphate groups to proteins, activating or deactivating them in cellular signaling pathways. Phosphorylases are enzymes that catalyze the addition of phosphate groups to molecules, often involved in energy metabolism. Phosphatases are enzymes that remove phosphate groups from molecules, reversing the actions of kinases and phosphorylases in cellular signaling pathways.
Can activating and deactivating the service usage on a cellphone take the cell phone off flight mode?
No. That's settings. If you really can't figure out how to change it back restore factory setting. If you have an android, go to shut it off, then when you have the screen up, it gives and option to take flight mode off. Search your settings high and low, otherwise.
Kinases and cyclins are internl factors that?
Kinases and cyclins are internal factors that play crucial roles in regulating the cell cycle. Kinases are enzymes that add phosphate groups to specific substrates, often activating or deactivating proteins involved in cell cycle progression. Cyclins are regulatory proteins whose levels fluctuate throughout the cell cycle, activating cyclin-dependent kinases (CDKs) to drive the transition between different phases. Together, they ensure proper timing and coordination of cell division and growth.
What is register globals in php?
Globals (global variables) are variables which are valid globally, which means they are available not only in a single function but "generally" throughout the script. register_globals is a switch which is defined in php.ini activating/deactivating this behavior. Since register_globals and the concept of globals is said to be removed for PHP6, it is advised to keep globals off and do not use global variables at all.
How would you expect the genes in the cells of your finger to compare with the genes in the cells of your liver?
Whether the DNA is from your finger, your liver, or your brain, the genes are all there. Depending on where the cell differentiated, different genes are activated while others are dormant. The genes in liver are also present in fingers, they just aren't activated. As of right now, scientists have no way of activating or deactivating a gene.
