Answer: Option (C) is the correct answer.
Explanation:
An ion is defined as a specie which is formed when a neutral atoms tends to gain or lose an electron.
When a neutral atom gain an electron then it forms a negative ion whereas when a neutral atom tends to lose an electron then it forms a positive ion.
For example, a neutral fluorine atom on gaining an electron will form ion. And, a sodium atom on losing an electron forms
ion.
When a group of atoms form ions then it tends to form polyatomic ions.
Thus, we can conclude that group of atoms that gains or loses electrons is called a polyatomic ion.
The longest chain of carbons will contain the highest number of carbon atoms.
Explanation:
question 3 - the longest chain have 7 carbon atoms
question 4 - the longest chain have 8 carbon atoms
question 1 - the longest chain have 5 carbon atoms
You may find in the attached picture the longest chain colored in blue for each of the compounds.
