Sir , I am a bsc chemistry student. I think you have made a mistake unknowingly in question no 29. The correct answer is A.lindlar catalyst not B.H2/pd because H2/pd will convert propyne to propane.....
@Suvojitsirscience10
@Suvojitsirscience10 10 месяцев назад
Correct .. But the actual question is Wrong .. In case of Hydrogen / pd , complete hydrogenation takes place .. but incase of Lindlar Catalyst , due to its poisonous behaviour the reaction stops with the conversion of Propene. Thank You so much .. But the commission enters Option B in their answer key
