To draw the skeletal structure line-angle (line-bond) mode of 2-isopropyltoluene and identify the number of hydrogen atoms bound to each carbon, follow these steps:
1. Start by identifying the main chain of the molecule. In this case, toluene is the main chain, consisting of a benzene ring with a methyl group attached.
2. Place the toluene structure in the center of your drawing. Draw a hexagon representing the benzene ring.

3. Next, identify the substituents in the molecule. In this case, there is an isopropyl (CH(CH3)2) group attached to the second carbon atom of the toluene ring.
4. Draw the isopropyl group as a three-carbon chain branching off from the second carbon of the toluene ring.

5. Finally, count the number of hydrogen atoms bound to each carbon atom in the structure.
- The carbon atom in the benzene ring has one hydrogen atom attached.
- The second carbon atom of the toluene ring, which is also the connection point for the isopropyl group, has two hydrogen atoms attached.
- The three carbon atoms in the isopropyl group have three, two, and three hydrogen atoms attached to them, respectively.
So, the number of hydrogen atoms bound to each carbon in the structure are as follows:
- Carbon in the benzene ring: 1 hydrogen
- Second carbon of the toluene ring: 2 hydrogens
- First carbon of the isopropyl group: 3 hydrogens
- Second carbon of the isopropyl group: 2 hydrogens
- Third carbon of the isopropyl group: 3 hydrogens
To draw the skeletal structure line-angle (line-bond) mode of 2-isopropyltoluene and identify the number of hydrogen atoms bound to each carbon, follow these steps:
Step 1: Start by drawing a benzene ring (a hexagon). This represents the toluene part of the molecule.

Step 2: Next, locate the carbon that is substituted with an isopropyl group. This carbon is connected to the benzene ring.

Step 3: Add the hydrogen atoms to each carbon. It's important to note that each carbon can have up to four bonds.

In this structure, each carbon atom is bound to the maximum number of hydrogen atoms possible, except for the tertiary carbon in the isopropyl group. This carbon only has one hydrogen atom bound to it.
Therefore, the number of hydrogen atoms bound to each carbon is as follows:
1. Carbon in the benzene ring: 1 hydrogen atom
2. Carbon in the benzene ring: 2 hydrogen atoms
3. Carbon in the benzene ring: 1 hydrogen atom
4. Carbon in the benzene ring: 1 hydrogen atom
5. Carbon in the benzene ring: 1 hydrogen atom
6. Carbon in the isopropyl group: 1 hydrogen atom
