Question

In the reaction, ${C_2}{H_5}OH\xrightarrow[{300C}]{{Cu}}X$ the molecular formula of X is:
A. ${C_4}{H_6}O$
B. ${C_4}{H_{10}}O$
C. ${C_2}{H_4}O$
D. ${C_2}{H_6}$

Answer 1

In chemistry, a chemical formula is a way of presenting information on the chemical proportions of atoms that comprise a certain chemical compound or molecule, using symbols, numbers, and sometimes other symbols of the chemical element, such as parentheses, dashes, brackets, commas, and signs of plus and minus.Ethanol is a volatile, flammable, and colourless liquid. The kind of alcohol that is used in alcoholic drinks and thermometers is ethanol. A colourless, flammable liquid is ethanol, also called ethyl alcohol and grain alcohol.

Complete step by step answer:
We need to know that the ethanol, with a faint characteristic odour, is a toxic, flammable, colourless liquid. It is a psychoactive agent in alcoholic beverages, a recreational drug, and an active ingredient. Naturally, ethanol is produced by yeast fermentation of sugars or through petrochemical processes, such as ethylene hydration. As an antiseptic and disinfectant, it does have medical uses. It is used in the synthesis of organic compounds and as a chemical solvent.
As we know that the oxidation is the loss of a molecule, particle, or ion to electrons during a reaction. When the oxidation state of a molecule, atom, or ion is increased, oxidation occurs. The opposite mechanism is called reduction, which happens when an atom, molecule, or ion reduces the gain of electrons or the oxidation state.
${C_2}{H_5}OH$, ethanol upon oxidation with Cu followed by heating at $300^\circ C$ gives aldehyde with molecular ${C_2}{H_4}O$ .
{C_2}{H_5}OH\xrightarrow[{300C}]{{Cu}}$$$${C_2}{H_4}O

So, the correct answer is Option C.

Note: To form aldehydes and carboxylic acids, primary alcohols can be oxidised; secondary alcohols can be oxidised to deliver ketones. Tertiary alcohol, on the other hand, cannot be oxidised without breaking the C-C bonds of the molecule. In the manufacture of polymers, biopolymers, coatings, adhesives, and prescription drugs, carboxylic acids and their derivatives are used. They can also be used as solvents, antimicrobials, food additives, and flavourings. Ketones are chemicals produced by your liver. When you do not have enough insulin in your body to convert sugar (or glucose) into energy, you generate it. Another source is required, so your body uses fat instead. Your liver converts a sort of acid into ketones and sends them into the bloodstream.
