The molecules of alkene family are represented by a general formula `C_n H_(2n)`.
What is the lowest value which can be assigned to n?

Explanation

To determine the lowest value of n that can be assigned to the alkene family represented by the general formula \( C_nH_{2n} \), we can follow these steps:

### Step 1: Understand the General Formula
The general formula for alkenes is given as \( C_nH_{2n} \). This means that for every n carbon atoms, there are \( 2n \) hydrogen atoms.

### Step 2: Identify the Minimum Value of n
To find the lowest value of n, we need to consider the smallest alkene that can exist. Alkenes are characterized by having at least one carbon-carbon double bond.
