Passage

Read the passage given below and answer the questions that follows:

Acetylene and other terminal alkynes (1-alkynes) are weakly acidic in character. The acetylenic hydrogen of such alkynes can be replaced by copper (1) and silver (I) ions. They react with ammonical solutions of cuprous chloride and silver nitrate to form the corresponding copper and silver alkynides.

This reaction can be used to distinguish between 2-alkynes and 1-alkynes. 1-Alkynes will give this test while 2-alkynes, will not give this test.
