Hydrocarbons having the general formula `C_nH_(2n -2)` are called___.

Explanation

To solve the question, "Hydrocarbons having the general formula C_nH_(2n -2) are called ___," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the General Formula**: The given general formula is C_nH_(2n - 2). This indicates a relationship between the number of carbon atoms (C) and hydrogen atoms (H) in the hydrocarbon.

2. **Understand the Structure**: The formula C_nH_(2n - 2) suggests that for every n carbon atoms, there are (2n - 2) hydrogen atoms. This formula is characteristic of hydrocarbons that contain at least one triple bond between carbon atoms.
