Question

Which of the following reagent used for
the conversion of 2-butyne into cis-2-
butene?​

Answer 1

Answer:

H / Lindlar Catalyst

Answer. React 2-butyne with H / Lindlar Catalyst , cis 2-butene is formed . The reagent is H / Lindlar Catalyst .

Explanation:

Answer 2

Answer:

React 2-butyne with H / Lindlar Catalyst , cis 2-butene is formed . The reagent is H / Lindlar Catalyst . It is a heterogeneous catalyst

Explanation:

Palladium metal is supported on either carbon or barium sulphate. Palladium metal is partially poisoned with quinoline or sulphur to decrease its reactivity. Since, you have poisoned the palladium catalyst, it will only reduce 2-butyene to cis-2-butene
