Question

CH4->CH3Br->CH3OH->HCHO->CH3OH

Answer 1

Нифига себе я такого не помню

Answer 2

The sequence you've provided appears to represent a series of chemical reactions. Let's break down each step:

1. CH4 (Methane) -> CH3Br (Methyl Bromide): In this step, methane (CH4) reacts with bromine (Br2) to produce methyl bromide (CH3Br). This reaction typically requires the presence of ultraviolet (UV) light or heat to initiate the reaction.

2. CH3Br (Methyl Bromide) -> CH3OH (Methanol): Methyl bromide (CH3Br) can be converted to methanol (CH3OH) through a substitution reaction, usually by reacting CH3Br with a nucleophilic species like hydroxide ions (OH-) in the presence of water (H2O).

3. CH3OH (Methanol) -> HCHO (Formaldehyde): Methanol (CH3OH) can be oxidized to formaldehyde (HCHO) through various oxidation methods, including oxidation with a strong oxidizing agent like chromic acid (H2CrO4).

4. HCHO (Formaldehyde) -> CH3OH (Methanol): Formaldehyde (HCHO) can undergo reduction to produce methanol (CH3OH) in the presence of a reducing agent, such as sodium borohydride (NaBH4).

So, the overall sequence of reactions is as follows: CH4 -> CH3Br -> CH3OH -> HCHO -> CH3OH

This sequence describes the conversion of methane (CH4) into methanol (CH3OH) via several intermediate reactions. Methane is a hydrocarbon, and the reactions involve halogenation, substitution, oxidation, and reduction processes to transform it into methanol, which is a simple alcohol.
