Hydrogen has the atomic number 1, and consists of one proton and one electron (the most common isotope of H). When it reacts, there is only one electron that can pair with another electron to form a covalent bond. Carbon, on the other hand, has four valence electrons and can therefore form a maximum of four covalent bonds with other atoms, which is why there in complex organic molecules are central carbons that bind either hydrogen or other atoms like oxygen, phosphorus and so on. The three-dimensional structure of carbon is also very favourable in this case.

∙ 10y agoBecause 'H' atom has only one electron and forms only one bond so it can not be a central atom....
Possible because hydrogen has one valance electron and in a Lewis acid is disassociated, so needs to be where it is steriochemically; the end(s) of the structure.

Which element is present in all organic molecules?
carbon i think
What element is found in all organic molecules?
All organic compounds contain carbon. In addition they may have hydrogen, oxygen, nitrogen, sulphur, halogens, phosphorus etc.
What two elements are present in hydrogen?
Hydrogen is, itself, a chemical element, and it is the most simple of all the elements. In hydrogen, one chemical element is present.
What distinguishes an organic molecule from and inorganic molecule?
Organic molecules have carbon while inorganic do not. An example of an organic molecule is that of proteins and carbohydrates. Inorganic examples are table salt and hydrochloric acid (stomach acid).
Which of these chemical elements is found in all organic molcules?
There are actually two. Carbon and Hydrogen
Which element is present in all organic molecules?
carbon i think
Organic molecules are made up of what?
The definition of an organic molecule is 'carbon containing.' The hydrogen is not necessary, but is often present.
What three elements occur in organic molecules?
Carbon (C), hydrogen (H), and usually oxygen (O) are the three elements that commonly occur in organic molecules. Carbon is the central element in organic compounds, while hydrogen and oxygen are often present in varying quantities and arrangements, giving organic molecules their unique properties and functions.
What element is found in all organic molecules?
All organic compounds contain carbon. In addition they may have hydrogen, oxygen, nitrogen, sulphur, halogens, phosphorus etc.
What are the substances that contain hydrogen but are not acids?
Many organic molecules contain hydrogen atoms and are not considered acids. Specifically, when carbon is bonded to hydrogen, this is considered an organic bond. There are organic acids as well though. In order for a substance to be acidic, it needs to have ionic hydrogen present (i.e. H+).
What are the functions of each of the four groups of molecules?
Four Major Categories of Organic MoleculesThe four major categories of organic molecules are lipids, nucleic acids, proteins and carbohydrates. The term "organic" refers to the fact that these molecules are present in or made by living organisms. These types of molecules also comprise more than one element, typically carbon-hydrogen bonds.
Main element of organic compound?
All organic compounds contain carbon and hydrogen; other elements may also be present. Organic compounds include methane (CH4), glucose (C6H12O6) and hydrogen cyanide (HCN).
What element makes a nutrient organic?
Hydrogen and carbon. Many other elements such as nitrogen, oxygen, sulfur, etc. may be present, but are not necessary to define a chemical as being organic.
Which element are present in all organic compounds?
Well the one element is ALWAYS carbon. You asked for Elements (plural) so... Nitrogen and Oxygen are also common but not required to be an organic compound.Phosphorus, sulfur, and Flourine are also present in some organic compounds.carbon and hydrogen minimally. Thus organic compounds are known as hydrocarbons.
What element is present in all living and once living compounds?
carbon is the element that is in all organic compounds.Others include O, H, and N.
What two elements are present in hydrogen?
Hydrogen is, itself, a chemical element, and it is the most simple of all the elements. In hydrogen, one chemical element is present.
How many molecules are present in a molecule of hydrogen?
there are 2 atoms of hydrogen in water
