Why is tryptophan included under aromatic amino acids rather than heterocyclic compounds?
Nivssmarty
It is both. Aromatic compounds need to be planar rings with contiguous pi-systems of 4n+2 electrons. Both rings in tryptophan are aromatic, and the five-membered ring is also a heterocycle.

Chemical compounds that contain carbon and hydrogen are called?
Compounds that contain carbon-hydrogen bonding are collectively termed organic compounds. These are simply compounds that would contain hydrogen and carbon elements.
How many elements are included in each compounds CCl4?
A molecule of carbon tetrachloride contains one carbon atom and four chlorine atoms.
What compounds are in a diamond?
Diamonds are allotropes of carbon. Trace amounts of other minerals may be included, and generally, these trace amounts give a diamond colour. Most commonly, nitrogen is included giving a diamond a yellow cast.
Why are covalently bonded molecular compounds never conductive?
Molecular compounds (these are electrically neutral) would be expected to be poor electrical conductors because the electrons in their covalent bonds are localised and difficult to "move". In any event molecules are separate and possible movement of electrons within the molecule would be difficult to propagate across the intermolecular gap. There are some interesting examples of covalent compounds that do conduct electricity. There are conductive polymers. Some are carbon based but there are others such as polythiazyl a sulfur nitrogen polymer. Strictly these polymers are molecular its just that the molecules are very large, and they are not usually included in the answers to questions like this. See links
Which compounds would produce an acidic solution when dissolved in water?
All ionic compounds Maybe, maybe not. who's to say its wrong
Why barbiturates are included in nucleic acids?
Barbiturates are not included in nucleic acids. They are a completely separately group of compounds.
How does the oil spill effect the air?
Crude oil is a mixture of hydrocarbons of all lengths and molecular shapes and other odourus compounds like hydrogen sulfide and mercaptans. Included in that mixture are many hydrocarbons which evaporate easily into the air. As a consequence when oil is spilt a portion of it is lost to the air and becomes a sulfidic or hydrocarbon vapor of light ends and aromatic organic compounds. This gives crude oil its characteristic odour.
What are three elements included in all organic compounds?
The three components that are needed to create small organic molecules are carbon, hydrogen and oxygen. These cells contain organic molecules and are essential to life.
Why are the noble gases not included on the table of electronegativities?
they already have full shells so they dont tend to form compounds
Chemical compounds that contain carbon and hydrogen are called?
Compounds that contain carbon-hydrogen bonding are collectively termed organic compounds. These are simply compounds that would contain hydrogen and carbon elements.
How do you get the symbols of Compounds?
Compounds have formulas that consist of symbols for elements and ions that are included in the molecules of the compound.The symbols (letters) are those of elements. These can be found on the periodic table. For example, H is hydrogen, He is helium and so on.
What is a inorganic chemistry?
A chemical that has no carbon.
How many elements are included in each compounds CCl4?
A molecule of carbon tetrachloride contains one carbon atom and four chlorine atoms.
What compounds are in a diamond?
Diamonds are allotropes of carbon. Trace amounts of other minerals may be included, and generally, these trace amounts give a diamond colour. Most commonly, nitrogen is included giving a diamond a yellow cast.
Which compounds has a ball-and-stick model that resembles a triangular pyramid?
Because no list of possible compounds from which to choose is given, presumably a generalized answer is desired. There is probably no exhaustive list, but methane and its tetra-fluoro, -chloro, -bromo, and -iodo derivatives would be included, along with the corresponding silanes.
What is fennel?
Fennel (Foeniculum vulgare) is a vegetable. It is a member of the family Apiaceae, along with other mostly aromatic plants with hollow stems and umbrella-like flower clusters. Included in this family are anise, caraway, carrot, celeriac, celery, chervil, coriander (including cilantro), cumin, hemlock, Queen Anne’s lace, parsley, dill, and parsnip.
Why are noble gases not in table 6.2?
Noble gases are not in Table 6.2 because they generally do not form compounds with other elements due to their stable electron configurations. Noble gases have a full outer shell of electrons, making them highly unreactive and unable to form bonds. Therefore, they do not readily participate in chemical reactions and are not included in the table that lists commonly occurring compounds.
