Name the following alcohols by carbinol system:
`HO.CH_(2)CH_(2)CH_(2)CH_(2)Ph`

Explanation

To name the given alcohol using the carbinol system, we will follow these steps:

### Step 1: Identify the Structure
The given compound is represented as `HO.CH₂CH₂CH₂CH₂Ph`. This indicates that we have a hydroxyl group (–OH) attached to a carbon chain that is connected to a phenyl group (Ph).

### Step 2: Determine the Carbon Chain
The carbon chain consists of four carbon atoms (C1, C2, C3, C4) followed by a phenyl group (Ph). Thus, we can denote the carbon chain as:
- C1: CH₂
