Respuesta :
The chain of atoms that are joined together to form the essential structure of an organic substance is called the skeletal structure.
The following sentences provide crucial guidelines for depicting skeletal structures:
1) Each heteroatom and the hydrogen atoms that are chemically connected to it.
2) A carbon atom can be found at the end of any line or at the intersection of any two lines.
3) Each carbon has four bonds because there are enough hydrogen atoms surrounding it.
These three option are the correct statements to describe the important rule for the drawing skeletal structures to represents the important structure of the organic compound.
The position of the carbon and hydrogen atoms are indicated by lines in the skeletal structure, line formula, or abbreviated formula for organic compounds. The endpoints of the lines and their intersections, as well as the hydrogen atom deduced from the number of bonds exhibited between each other, illustrate where the carbon atoms are located in the skeletal structure.
Hetero-atoms are any atoms other than carbon and hydrogen. The only hydrogen atoms that must be present in skeletal structure are those that are physically connected to a hetro atom.
