need help with reagents and conditions!

In each reaction box, place the best reagent and conditions from the list below In each reaction box, place the best reagent and conditions from the list below

Answer 1

Concepts and reason

The concept used to solve this problem is chemical reactions of dihalides and alkynes.

For a chemical reaction to occur, some substances are needed which are termed as reagents. These reagents react with the reactant molecules and initiate the chemical reaction in the reaction medium.

Fundamentals

Reagents are the substances which are used for the analysis or to bring a desire change in the chemical reaction.

Sodium amide is a strong base and it abstract the most acidic proton from the reactant molecule when added as a reagent in the chemical reaction. ${{\rm{H}}_{\rm{2}}}{\rm{,Pt}}$ and sodium in liquid ammonia are used as reducing agents in the chemical reactions and water in acidic and in basic medium is used for oxidation of the compounds. ${\rm{mCPBA}}$ is a reagent which is used to carry out epoxidation of alkenes.
