Indicate substance X, which corresponds to the CH4-X-C2H4 transformation scheme. 1) C2H2 2) C2H6 3) CH3Br 4) C2H50H
CH4 – C2H2 – C2H4.
Substance X – acetylene C2H2.
Methane at very high temperatures (1500 degrees) turns into acetylene.
2CH4 = C2H2 + 3H2
Further, when acetylene is hydrogenated, ethylene CH2 = CH2 is obtained. Hydrogenation is carried out with lithium aluminum hydride (LiAlH4), diisobutyl lithium aluminum hydride (DIBAL), sodium in liquid ammonia, hydrogen in the presence of metals.
Answer: 1) C2H2.
