Draw the skeletal (line-angle) structure for 2,2-dimethyl-4-propyloctane.

Total bonds means total individual lines (single bond = 1 line, double bond = 2 lines, triple bond = 3 lines).

Enter each of your answers as integers.
How many total carbons are in the structure?
How many primary carbons are in the structure?
How many secondary carbons are in the structure?
How many tertiary carbons are in the structure?
How many quaternary carbons are in the structure?

Answer :

Total carbons are in the structure = 13

Primary carbons are in the structure = 5

Secondary carbons are in the structure = 6

Tertiary carbons are in the structure = 1

Quaternary carbons are in the structure = 1

Explanation :

Primary carbon : It is a carbon atom that is bound to only 1 carbon atom.

Secondary carbon : It is a carbon atom that is bound to 2 carbon atom.

Tertiary carbon : It is a carbon atom that is bound to 3 carbon atom.

Quaternary carbon : It is a carbon atom that is bound to 4 carbon atom.

As we are given the name of compound is, 2,2-dimethyl-4-propyloctane.

In this compound, eight carbon are align in a straight line, two methyl group are attached at 2nd position of the carbon in main chain and a propyl group that is three membered carbon chain is attached at 4th position of the carbon in main chain.

The given compound skeletal structure is shown below.

i'm pretty sure its b i might be wrong though!

it is the most commonly accepted one
