To obtain monochloroethane from ethylene, chlorine gas (Cl2) must be added. The reaction between ethylene and chlorine gas results in the substitution of one hydrogen atom in ethylene with a chlorine atom, forming monochloroethane. This reaction is known as chlorination and is commonly used in the production of various chloroalkanes. **

Monochloroethane cannot be formed in any of the reactions because it requires the substitution of two hydrogen atoms in ethane with chlorine atoms. The reactions provided only involve the addition of one chlorine atom to the ethane molecule, resulting in the formation of chloroethane. To form monochloroethane, a different reaction mechanism, such as free radical chlorination, would be needed to replace both hydrogen atoms with chlorine atoms. **

Monochloroethane cannot be formed in any of the reactions because it is a primary halogenoalkane, meaning that the carbon atom bonded to the halogen is only attached to one other carbon atom. In the reactions provided, the starting materials are either ethene or ethanol, both of which do not have a primary carbon atom bonded to the halogen. Therefore, monochloroethane cannot be formed as a product in these reactions. **

Fashion jewelry can stain if it comes into contact with certain substances such as water, sweat, perfume, lotion, or other chemicals. The metal in fashion jewelry can react with these substances and cause discoloration or staining. To prevent staining, it's important to remove fashion jewelry before swimming, exercising, or applying lotions or perfumes. Additionally, storing fashion jewelry in a dry and clean environment can help prevent staining. **

Fashion jewelry rings are decorative rings that are designed to be trendy and stylish, rather than expensive or made with precious metals and gemstones.

They come in a wide variety of designs and styles, making them a popular choice for fashion-forward individuals. **

As an AI, I don't have the ability to wear jewelry accessories. However, many people enjoy wearing jewelry as a form of self-expression and to enhance their outfits. Some people like to wear jewelry to make a fashion statement, while others wear it for sentimental reasons or as a symbol of status. Ultimately, whether or not someone likes to wear jewelry accessories is a matter of personal preference. **

Fashion jewelry and gold-plated jewelry are not the same. Fashion jewelry refers to any type of jewelry that is made with non-precious metals, such as brass or copper, and may be adorned with imitation gemstones or crystals. On the other hand, gold-plated jewelry is made by covering a base metal, such as brass or sterling silver, with a thin layer of gold through a process called electroplating. While both types of jewelry can be stylish and affordable, gold-plated jewelry contains a layer of real gold, making it more valuable than fashion jewelry. **
