विकल्प

• Propyne \[\ce{C3H6}\]

• Propyne \[\ce{C3H4}\]

• Butyne \[\ce{C4H8}\]

• Butyne \[\ce{C4H6}\]

Answer 1

The name and formula of third member of homologous series of alkyne is Butyne \[\ce{C4H8}\].
Explanation:

Butyne is the third in the homologous series of alkynes. The chain consists of four carbon atoms, with a triple bond between the second and third. Therefore, its chemical formula is \[\ce{C4H8}\].
