Hint: The answer to this question, is based on the concept of general chemistry that deals with the concept of the carbon atom which is bound to the number of hydrogen atoms in the case of an alkane.
Complete Solution :
Let’s understand what are primary carbons, secondary carbons and tertiary carbons in alkanes.
-alkanes in which the carbon atom is bonded with three hydrogen atoms is known as primary carbon.
-alkanes in which the carbon atom is bonded with two hydrogen atoms and with one other carbon atom is known as secondary carbon. This also applies for alkenes as there is presence of double bond between the carbon atoms and then particulate carbon is attached to one hydrogen atom.
-alkanes in which the carbon atom is bonded with one hydrogen atom and two other carbon atoms is known as tertiary carbon.
The total primary carbon present in the given compound is 6. The primary carbons are mentioned below:
So, the correct answer is “Option D”.
Note: In general, if a carbon atom is attached to only one carbon atom it is known as a primary carbon. Similarly, if a carbon atom is attached to two other carbon atoms it is known as secondary carbon and if a carbon atom is attached to three other carbon atoms then it is known as tertiary carbon.
