Which of the following alkenes have more value of heat of hydrogenation than

The coordination compound used as catalyst for the hydrogenation of alkenes is

Identify the wrong statement regarding addition of Br_2//"CCI"_4 to alkene : Decolourisation of Br_2//"CCI"_4 without liberation of HBr is a sure test for unsaturation, It is an electrophilic addition, It is an anti addition reaction, None of the steps in the reaction mechanism involves attack by a nucleophile.

Alkenes on catalytic hydrogenation give alkanes. The reactions are exothermic. The heat of hydrogenation is a measure of stability of alkene. Lesser the heat of hydrogenation more stable the alkene. The relative rate of catalytic hydrogenation of the following alkenes is

Alkenes on catalytic hydrogenation give alkanes. The reactions are exothermic. The heat of hydrogenation is a measure of stability of alkene. Lesser the heat of hydrogenation more stable the alkene. The correct order of heat of hydrogenation is

Alkenes on catalytic hydrogenation give alkanes. The reactions are exothermic. The heat of hydrogenation is a measure of stability of alkene. Lesser the heat of hydrogenation more stable the alkene. . Which of the following statement is true ?

Identify the incorrect statement/statements: i) Alkynes are more reactive than alkenes towards electrophilic addition reaction ii) Alkynes are less reactive than alkenes towards electrophilic addition reaction iii) Alkynes decolourise Br_2 water iv) Addition of HBr to alkynes in presence of peroxide proceeds via Markownikoff's rule : i and ii, ii and iii, I and iv, ii and iv

Acid catalysed hydration of alkene gives alcohol. In this reaction addition of water takes place according to Markownikoff's rule. Since intermediate carbocation is formed in this reaction, rearrangement of carbocation takes place. In oxymercuration-demercuration reaction hydration of alkene takes place according to Markownikoff's rule. Oxymercuration demercuration is a better process than the catalytic hydration of alkene because in oxymercuration-demercuration, no rearrangement is possible. In hydroboration oxidation, hydration of alkene takes place as if it is according to anti-Markownikoff's addition. In hydroboration oxidation reaction rearrangement is not possible. Both in oxymercuration-demercuration and hydroboration oxidation intermediate carbocation are not formed. The product formed in the following reaction is
