2-Ethoxy-2,3-dimethylbutane reacts with concentrated aqueous HI to form two initial organic products (A and B). Further reaction

Leno4ka [110]

Answer:

A = 2-iodo-2,3-dimethylbutane

B = Ethanol

C = Iodoethane (also called ethyl-iodide)

Explanation:

2-Ethoxy-2,3-dimethylbutane reacts with conc. HI to cleave the oxy-functional group.

On one end, ethanol is formed and on the other hand, 2-iodo-2,3-dimethylbutane is formed.

But ethanol reacts further with conc HI to give iodoethane.

Therefore,

A = 2-iodo-2,3-dimethylbutane

B = Ethanol

C = Iodoethane (also called ethyl-iodide)

This is all shown in the attached image.

Feeding levels within an ecosystem are

alisha [4.7K]

Answer:

C. trophic levels

Explanation:

Trophic levels are the feeding positions of all organisms in a specific ecosystem. There are five main trophic levels, or feeding levels.

-----------

Habitats are the environment in which organisms live. They are not feeding levels.

Taxonomic levels are a way of classifying species. They consist of (in order) domain, kingdom, phylum, class, order, family, genus, and species. They are not feeding levels.

Cladograms are branching diagrams that show the relationship between multiplt organisms/species. It too is not a feeding level.

Thus, is answer is C.

hope this helps!

matrenka [14]

The kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.

<h3>What is an amino acid?</h3>

An amino acid refers to a simple and organic chemical compound that consist of an acidic carboxyl group (COOH), a basic amino group ( $NH_2$ ), and a unique side chain group.

<h3>What is a protein?</h3>

A protein can be defined as a <u>hydrophilic</u>, macromolecule (polymer) that is formed as a result of the union of many amino acids.

Generally, a protein contains the following chemical elements:

Oxygen (O) atoms

Hydrogen (H) atoms

Sulfur (S) atoms

In conclusion, the kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.
