What is wrong with the following names ? Drawn the structures they represent and given their (a) correct IUPAC name, (b) write the corresponding corresponding bond line structures.
I. 1,1-Dimethyl pentane
II. 2-Methyl-2-propyl hexane
III. 3-Dimethyl pentane
IV. 4,4-Dimethyl-3-ethyl pentane
V. 3-Isopropyl pentane
VI. 3-Chloro-4-methyl pentane
VII. 4-(2-Methyl ethyl) heptane

Explanation

To solve the problem, we will analyze each of the given names, draw their structures, and provide the correct IUPAC names along with the corresponding bond line structures.

### Step 1: Analyze and Draw Structures

#### I. 1,1-Dimethylpentane
1. **Draw the structure**:
- Pentane has 5 carbon atoms in a straight chain.
- At position 1, there are two methyl (CH₃) groups.
