WebCorrect option is B) Iodination is reversible since formed HIis a strong reducing agent and reduces the alkyl iodide back to alkane. CH4 +I2 ⇌CH3 I+HI. Iodination is carried out … Web(a) Nitration of alkane: The process which involves the replacement of hydrogen atom of alkanes by nitro group (-NO2) is known as nitration of an alkane. It can be carried out in two ways:(i) Liquid phase nitration; In this method higher alkane is heated with fuming HNO3 at 413 K under pressure.(ii) Vapour phase nitration: Lower member of alkanes can be …
WebThe iodination of benzene is a reversible reaction. Therefore, yield of C 6 H 5 I is very poor because HI combines with C 6 H 5 I and forms back the reactants. In the presence of oxidizing agent like HIO 3 or HNO 3 , the co-product HI is oxidised to iodine and iodination proceeds favourably in the forward direction. Web31 jul. 2024 · The alkenes are like the alkanes in being nonpolar compounds (Section 4-1) and it may come as a surprise that many important reactions of alkenes are heterolytic …
