Birch reduction : Birch reduction involves controlled reduction of alkynes & atomic compounds in the preseance of alkali metals & alcohol. It provides a method to sterospecifically prepare alkenes of E- configuration R - C -= C -R overset(M,EtOH)to The characteristic type of reaction of alkynes is electrophilic addition reaction like alkenes. The alkynes show various reactions such as halagenation, hydration, hydrogenation etc... 0.40 5g sample of hydrocarbon occupies 229.54ml at 100^(@)C & 1 atm pressure. It decolouses KMnO_4 & Br_2water. When it reacts with dil. H_2SO_4 under appropriate conditions methyl ethyl, ketone is formed The hydrocarbon is

Answer» More REACTIVE than butane towards `Br_2 // C Cl_4 & H_2// PT ` Less reactive than butane towards `Br_2 // C Cl_4 & H_2// Pt ` More reactive than butane towards `Br_2// C Cl_4`, but less reactive towards `H_2// Pt` Less reactive than butane towards `Br_2// C Cl_4`, but more reactive towards `H_2// Pt` Solution :alkene are more reactive than alkynes towards hydrogenation and electrophilic ADDITION REACTIONS.
