Select the formulae of alkanes, alkenes and alkynes from the following:
`CH_4, C_2H_4, C_2H_6, C_2H_2, C_3H_8, C_3H_4, C_4H_10, C_4H_8, C_4H_6, C_3H_6`

Explanation

To categorize the given hydrocarbons into alkanes, alkenes, and alkynes, we will use their general formulas:

1. **Alkanes**: General formula is \( C_nH_{2n+2} \)
2. **Alkenes**: General formula is \( C_nH_{2n} \)
3. **Alkynes**: General formula is \( C_nH_{2n-2} \)

Now, let's analyze each compound one by one:
