Neopentyl alcohol, (ch3)3cch2oh, cannot be dehydrated to an alkene without rearrangement. what is the chief product of dehydration?
Answers
Dehydration is removal of water.
In alcohols dehydration is α-β elimination or 1,2 elimination, it means the hydroxyl group will be removed from α-carbon while the hydrogen will be removed from near by carbon.
In case of neopentyl alcohol there is no β hydrogen present on the β carbon [as shown in figure].
The only possible way for it to undergo dehydration is by rearrangement.
The process or mechanism can be understood as:
so the chief product is 2-methylbut-2-ene

Final answer:
Group 16 elements, also known as chalcogens, commonly react with nonmetals to form compounds.
Explanation:
In chemistry, group 16 elements are known as the chalcogens. Chalcogens react with various groups of elements, including metals and nonmetals. However, their reactions with nonmetals are more common.For example, sulfur (group 16) readily reacts with most nonmetals to form compounds. The resulting compounds can vary depending on the specific nonmetal involved. Therefore, the group that would most likely react with group 16 to form a compound is the nonmetals group.

What is a compound?
A compound is a substance that consists of two or more different elements chemically bonded together in fixed proportions. In a compound, the constituent elements lose their individual properties and form new chemical properties unique to the compound.
The study of compounds is central to chemistry, as it involves understanding the structure, composition, and reactivity of substances. Compound analysis and synthesis play vital roles in various scientific fields, such as materials science, pharmaceuticals, and environmental science.

What is element?
A pure substance made up entirely of atoms with almost the same number of protons in respective nuclei was known as an element.
What is atoms?
Atoms are "the fundamental building components of matter," according to Wikipedia. It is the lowest fundamental unit of matter which thus possesses chemical element qualities.

Carbon dioxide has a low boiling point because of its weak intermolecular forces (London dispersion forces) and its linear molecular structure, which results in a nonpolar molecule.
Carbon dioxide has a very low boiling point due to its intermolecular forces and molecular structure.
1. Intermolecular forces: Carbon dioxide molecules are held together by weak London dispersion forces. These forces are relatively weak compared to other intermolecular forces such as hydrogen bonding or dipole-dipole interactions. London dispersion forces result from temporary shifts in electron density, causing a temporary dipole. Since carbon dioxide has a linear molecular shape, the induced dipoles can align more easily, increasing the strength of the London dispersion forces. However, these forces are still weaker compared to other molecules with more complex structures.
2. Molecular structure: Carbon dioxide consists of one carbon atom bonded to two oxygen atoms. The oxygen atoms are highly electronegative, pulling the shared electrons towards themselves, resulting in a polar molecule. However, due to its linear shape, the polar bonds cancel each other out, making the molecule nonpolar overall.
These weak intermolecular forces, combined with the nonpolar nature of carbon dioxide, contribute to its low boiling point. The weak London dispersion forces between carbon dioxide molecules are easily overcome by the thermal energy of the surroundings, causing the molecules to separate and transition from the liquid to the gaseous state at a relatively low temperature. This is why carbon dioxide exists primarily as a gas at room temperature and atmospheric pressure.
