When 1-butyne is treated with excess Br2 in CCl4, the product formed is 1,1,2,2-tetrabromobutane.

Here's the step-by-step process:

1. 1-butyne is an alkyne, which means it has a triple bond between two of its carbon atoms.

2. When it is treated with excess Br2 (bromine), a halogenation reaction occurs. This is a type of reaction where one or more hydrogen atoms in the hydrocarbon (1-butyne in this case) are replaced by halogen atoms (bromine atoms in this case).

3. Because there is an excess of Br2, both the pi bonds of the triple bond in 1-butyne are broken and replaced by two Br atoms each.

4. The product of this reaction is 1,1,2,2-tetrabromobutane, which means that the first and second carbon atoms are each bonded to two bromine atoms.
