Answer:
The product formed is orthonitrophenol
Explanation:
The compound orthonitrophenol is formed when ortho-bromonitrobenzene is treated with NaOH at elevated temperature.
The reaction leads to the formation of an intermediate stabilized by resonance. This intermediate can not be formed by the meta isomer because a resonance stabilized intermediate can not be formed and the product is not stabilized by intramolecular hydrogen bonding hence this reaction will not occur.
It described a nucleus surrounded by a large volume of space.
Answer:
Vitamin D
Explanation:
Without Vitamin D animals (humans included) will start to degrade and organs will shut down
Answer:
One orientation
Explanation:
A s orbital is a sphere like shape that surrounds the atomic nucleus that consists of electrons that can be found at the highest or lowest region of the orbital. S orbitals only consist of "one orientation" and is commonly mistaken by the p orbital because the p orbital also consists of electrons that can be found the most.
