Answer 2

The compound is chloroform.

• The first member of the alkyne series is ethyne or acetylene.
• Chloroform on heating with silver powder produces acetylene along with silver chloride.
• The reaction is as follows-
• $2CHCl_3+6Ag\rightarrow C_2H_2+6AgCl$.
• Thus in this reaction, two moles of chloroform react with six moles of silver to form one mole of acetylene along with six moles of silver chloride.
