Answer
The picture is attached below.
The hydrogen atoms shown in purple are primary.
The hydrogen atoms shown in black are secondary.
The hydrogen atom shown in red is tertiary.
Work Step by Step
The hydrogen atoms shown in purple are bonded to a carbon atom that is bonded to 1 R group. These hydrogen atoms are therefore primary.
The hydrogen atoms shown in black are bonded to a carbon atom that is bonded to 2 R groups. These hydrogen atoms are therefore secondary.
The hydrogen atom shown in Red is bonded to a carbon atom that is bonded to 3 R groups. This hydrogen atom is therefore tertiary.
