Complete And Name Products Of Chemical Equations

Hey guys! Let's dive into completing these chemical equations and naming the products. Understanding these reactions is super important in chemistry, and we'll break it down step by step. We'll make sure everything is crystal clear so you can ace those chemistry tests! So, grab your notebooks, and let's get started!

Completing Chemical Equations

In this section, we're going to tackle the given chemical equations. We'll identify the reactants, predict the products, and balance the equations to ensure the law of conservation of mass is followed. Let's dive deep into each reaction and understand what's happening at the molecular level. Remember, chemistry is all about understanding how different substances interact with each other, so let's get to it!

Equation A: $CH_2=CH_2 + H_2

ightarrow$ ?

Alright, let's kick things off with equation A: $CH_2=CH_2 + H_2 ightarrow$ ?. In this reaction, we have ethene ($CH_2=CH_2$) reacting with hydrogen ($H_2$). This type of reaction is known as hydrogenation, where hydrogen atoms are added across a double or triple bond in an unsaturated hydrocarbon. Ethene, with its carbon-carbon double bond, is a prime candidate for this process. The hydrogen molecule ($H_2$) will break apart, and each hydrogen atom will attach to one of the carbon atoms in the double bond. This process converts the double bond into a single bond, effectively saturating the hydrocarbon.

The reaction can be represented as follows: $CH_2=CH_2 + H_2 ightarrow CH_3CH_3$. So, what's the product here? It's ethane ($CH_3CH_3$)! Ethane is a saturated hydrocarbon, meaning it only has single bonds between carbon atoms. This transformation from ethene (an alkene) to ethane (an alkane) is a classic example of an addition reaction. You'll often see this reaction using a metal catalyst, like platinum (Pt), palladium (Pd), or nickel (Ni), to speed things up. These catalysts provide a surface where the hydrogen and ethene can adsorb and react more easily. Without the catalyst, the reaction would be much slower due to the high activation energy required to break the hydrogen-hydrogen bond.

Equation B: $CH

CH + 2Cl_2 ightarrow$ ?

Now, let's jump into equation B: $CH CH + 2Cl_2 ightarrow$ ?. In this equation, we have ethyne ($CH CH$), also known as acetylene, reacting with chlorine ($2Cl_2$). Ethyne has a carbon-carbon triple bond, making it even more reactive than ethene. This reaction is a halogenation reaction, where halogen atoms (in this case, chlorine) are added across the multiple bonds. Since we have 2 molecules of chlorine ($2Cl_2$), we can expect two addition reactions to occur.

The first chlorine molecule will add across the triple bond, converting it into a double bond. The second chlorine molecule will then add across the double bond, converting it into a single bond. The full reaction looks like this: $CH CH + 2Cl_2 ightarrow CCl_2CHCl_2$. So, what's our product this time? It's 1,1,2,2-tetrachloroethane. This molecule has four chlorine atoms attached to the two carbon atoms, making it a fully halogenated ethane derivative. Halogenation reactions are crucial in organic chemistry for synthesizing various halogenated compounds, which have numerous applications in industries such as pharmaceuticals and materials science. Understanding the step-by-step addition of halogens to unsaturated hydrocarbons is key to mastering organic reactions.

Naming the Products Formed

Alright, now that we've completed the equations, let's talk about naming the products. This is a crucial part of chemistry because a compound's name tells us a lot about its structure and properties. We'll use the IUPAC nomenclature system, which is the standard for naming organic compounds. So, let's break down the names and see what they tell us about the molecules we've created.

Naming the Product of Equation A: Ethane ($CH_3CH_3$)

The product of equation A is ethane ($CH_3CH_3$). This is a simple alkane, meaning it's a hydrocarbon with only single bonds. The name "ethane" follows the IUPAC nomenclature rules. The prefix "eth-" indicates that there are two carbon atoms in the molecule. The suffix "-ane" tells us that it is an alkane, meaning all carbon-carbon bonds are single bonds. Ethane is a colorless, odorless gas at room temperature and is commonly used as a fuel. It's also a significant component of natural gas. The structure of ethane is straightforward: two carbon atoms connected by a single bond, with each carbon atom bonded to three hydrogen atoms. This simple structure gives ethane its stability and predictable chemical behavior.

Naming the Product of Equation B: 1,1,2,2-Tetrachloroethane ($CCl_2CHCl_2$)

Now, let's tackle the name of the product from equation B: 1,1,2,2-tetrachloroethane ($CCl_2CHCl_2$). This name might look a bit intimidating, but it's quite systematic once you break it down. The "ethane" part tells us that the backbone of the molecule is a two-carbon chain, just like in ethane. The prefix "tetrachloro-" indicates that there are four chlorine atoms in the molecule. Now, let's look at the numbers: "1,1,2,2-" tells us the positions of these chlorine atoms on the carbon chain.

The numbers indicate that two chlorine atoms are attached to the first carbon atom (1,1) and two chlorine atoms are attached to the second carbon atom (2,2). Putting it all together, 1,1,2,2-tetrachloroethane is a derivative of ethane where all four hydrogen atoms have been replaced by chlorine atoms. This compound is a colorless liquid with a sweet odor and has been used as a solvent and in various industrial applications. Understanding how to name compounds like this is crucial for identifying and discussing complex organic molecules accurately.
