We can't draw structures on the board.
The first one is propene + chlorine ==> 1,2-dichloropropane.
The second is
ammonia + pentanoic acid ==> pentanamide + water
pentane + oxygen ==> carbon dioxide + water.
1. Reaction: Addition of Chlorine to Propene
Reactants: C3H6 (Propene), Cl2 (Chlorine)
Product: C3H6Cl2 (1,2-Dichloropropane)
Explanation: In the reaction, propene (C3H6) reacts with chlorine (Cl2) to form 1,2-dichloropropane (C3H6Cl2). To write the structural formula, we represent each element by its symbol and connect them using lines to show the bonding. The structural formula for propene is CH2=CHCH3, indicating a double bond between the carbon atoms. Chlorine has a single bond between its atoms (Cl-Cl). Therefore, the complete structural formula for the reaction is:
H H Cl Cl

2. Reaction: Condensation Reaction between Ammonia and Butanoic acid
Reactants: NH3 (Ammonia), C4H9COOH (Butanoic acid)
Products: C4H9CONH2 (Butanamide), H2O (Water)
Explanation: In this reaction, ammonia (NH3) reacts with butanoic acid (C4H9COOH) to form butanamide (C4H9CONH2) and water (H2O). The structural formula for butanoic acid is CH3CH2CH2COOH, and for ammonia, it is NH3. To write the structural formula for the products, we replace a hydrogen atom from butanoic acid with the NH2 group from ammonia, leading to the formation of butanamide. Meanwhile, H2O is formed as a byproduct of the reaction. Therefore, the complete structural formula for the reaction is:
H H H O H

3. Reaction: Combustion of Pentane
Reactants: C5H12 (Pentane), O2 (Oxygen)
Products: CO2 (Carbon Dioxide), H2O (Water)
Explanation: This reaction involves the combustion of pentane (C5H12) in the presence of oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). Pentane has a straight chain of five carbon atoms, so its structural formula is CH3(CH2)3CH3. When pentane reacts with oxygen, it undergoes complete combustion, resulting in the formation of carbon dioxide and water. Therefore, the complete structural formula for the reaction is:
H H H H H

Additionally, two molecules of water (H2O) are formed in the reaction.
