To distinguish between ethylene (C2H4) and acetylene (C2H2), we can perform a couple of chemical tests based on their structural differences and reactivity. Here’s a step-by-step explanation of the distinctions: ### Step 1: Identify the Structures - **Ethylene**: The molecular formula is C2H4, and it has a double bond between the two carbon atoms (CH2=CH2). - **Acetylene**: The molecular formula is C2H2, and it has a triple bond between the two carbon atoms (CH≡CH). ### Step 2: React with Sodium Hydroxide (NaOH) - **Ethylene**: When ethylene is treated with NaOH, no reaction occurs because it does not have any acidic hydrogen atoms. ...
