Solution
The major product obtained when 1-hexyne is treated with H2 and Lindlar's catalyst is cis-2-hexene.
Here's the step-by-step process:
-
1-hexyne is an alkyne, which is a hydrocarbon with a triple bond.
-
When 1-hexyne is treated with hydrogen (H2) in the presence of Lindlar's catalyst, the triple bond is partially reduced to a double bond.
-
Lindlar's catalyst is a special catalyst that only reduces the triple bond to a cis double bond, not all the way to a single bond.
-
Therefore, the product of this reaction is cis-2-hexene, which is an alkene with a cis double bond at the 2nd carbon.
So, the correct answer is cis-2-hexene.
