Question:
CH$_3$-C$\equiv$C-CH$_3$ \(\xrightarrow{\text{H}_2/\text{Pd-CaCO}_3}\) (X)
\(\xrightarrow{\text{Na/Liq. NH}_3}\) (Y)
Select the correct statement:
CH$_3$-C$\equiv$C-CH$_3$ \(\xrightarrow{\text{H}_2/\text{Pd-CaCO}_3}\) (X)
\(\xrightarrow{\text{Na/Liq. NH}_3}\) (Y)
Select the correct statement:
Show Hint
Cis and trans isomers are geometrical isomers, a type of stereoisomer that differs in the spatial arrangement of substituents around a double bond.
Updated On: Feb 2, 2026
- Boiling point of X<Y
- Dipole moment Y>X
- X and Y are stereoisomers of each other
- Melting point of X>Y
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Identify the compounds X and Y.
X is cis-1-butene, and Y is trans-2-butene, as the reactions involve catalytic hydrogenation and reduction with Na in liquid ammonia. These transformations change the geometry of the alkene, leading to cis and trans isomers.
Step 2: Conclusion.
Since cis- and trans- isomers are stereoisomers, the correct answer is (3).
