Question

Кабрид кальция -> венилацетилен; кабрид алюминия -> этаналь; уголь -> 1,1,2,2-тетрабромэтан помогите решить, пожалуйста

Answer 1

CaC2 + H2O = Ca(OH)2 + C2H2
2C2H2=(AlCl3) CH2=CH-C≡CH

3C + CaO = CaC2 + CO
CaC2 + H2O = Ca(OH)2 + C2H2
C2H2 + 2Br2 = C2H2Br4

Al4C3 + 12 H2O = 4 Al(OH)3 + 3 CH4
2CH4(t)=C2H2+3H2
C2H2+HOH(t,Hg2+) = CH3-COH

Answer 2

Chemical Reactions:

The given chemical reactions can be represented as follows:

1. Calcium Carbide to Vinylacetylene: - The reaction of calcium carbide (CaC2) with water can produce acetylene gas, which can then undergo a reaction to form vinylacetylene. - The chemical equation for the reaction is: ``` CaC2 + 2H2O → Ca(OH)2 + C2H2 C2H2 → C4H4 ``` - This process involves the conversion of calcium carbide to vinylacetylene.

2. Aluminum Carbide to Ethanal: - Aluminum carbide is not a commonly known compound, and there is no direct evidence of its reaction to form ethanal (acetaldehyde). - It's important to note that aluminum carbide may not readily react with water or other common substances to produce ethanal.

3. Coal to 1,1,2,2-Tetrabromoethane: - The transformation of coal to 1,1,2,2-tetrabromoethane involves several complex chemical processes and is not a direct or simple reaction. - Coal is a complex mixture of organic compounds and undergoes various chemical processes to produce different products. The direct conversion to 1,1,2,2-tetrabromoethane is not a well-documented or straightforward reaction.

It's important to note that the second and third reactions provided may not have direct, well-established pathways for the given transformations. If there are specific contexts or conditions under which these reactions are proposed, further details would be necessary to provide a more accurate assessment.
