The reagents used to accomplish the given transformation should be draw and identified. Concept Introduction : Reduction reaction: The alkenes or alkynes can be reduced to alkanes with D 2 (Deuteration) or 2 H hydrogen atom in the presence of metal catalyst ( Pd/H 2 ) (Lindlar’s catalyst). The new C-H σ bonds are formed simultaneously from H atoms absorbed into the metal surface. Soda amide: The strong base of NaNH 2 /NH 3 will deprotonates the alkynes, alcohols and other organic functional groups with acidic protons such as asters and ketones. It is a strong base and excellent nucleophile. It is used to deprotonate the weak acids and also used for elimination reaction. Birch Reduction: The conjugated alkynes or benzene in the presence of sodium metal in liquid ammonia which produce a non-conjugated system is called birch reduction. The alkyne involves sodium ( Na ) /NH 3 . This end up in reducing the alkyne to Trans ( E ) alkene. Landlar catalyst:

Interpretation Introduction

Interpretation:

The reagents used to accomplish the given transformation should be draw and identified.

Concept Introduction:

Reduction reaction: The alkenes or alkynes can be reduced to alkanes with $D2$ (Deuteration) or $2H$ hydrogen atom in the presence of metal catalyst $(Pd/H2)$ (Lindlar’s catalyst). The new $C-H σ$ bonds are formed simultaneously from $H$ atoms absorbed into the metal surface.

Soda amide: The strong base of $NaNH2/NH3$ will deprotonates the alkynes, alcohols and other organic functional groups with acidic protons such as asters and ketones. It is a strong base and excellent nucleophile. It is used to deprotonate the weak acids and also used for elimination reaction.

Birch Reduction: The conjugated alkynes or benzene in the presence of sodium metal in liquid ammonia which produce a non-conjugated system is called birch reduction. The alkyne involves sodium $(Na)/NH3$ . This end up in reducing the alkyne to Trans (E) alkene.
