Each carbon atom covalently bonds with atoms of carbon, hydrogen, oxygen, and nitrogen describes why carbon can form a wide variety of organic compounds. thus, option B is correct.
Valency is the combining power of an element. Elements in the same group of the periodic table have the same valency. The valency of an element is related to how many electrons are in the outer shell.
Carbon can form a wide variety of organic compounds because Each carbon atom covalently bonds with atoms of carbon, hydrogen oxygen, and nitrogen. a carbon atom can have 4 single valence electrons around it. This allows it to form covalent bonds with many different atoms.

(2) structural formula (4) IUPAC name
Answer: Option (1) is the correct answer.
Explanation:
When two different molecules represent same molecular formula but different arrangement of atoms then they are known as isomers.
Whereas physical properties are the properties which determines the state of object or substance. That is, property which can be observed.
For example, wood is brown in color.
On the other hand, when arrangement of atoms are represented by the formula of a molecule then it is known as structural formula.
Thus, we can conclude that all isomers of octane have the same molecular formula.
