D
4
Ask EduPadi AI for a detailed answer
Correct Option: A
Butene (C4H8) has different forms. Considering 2-butene (CH3-CH=CH-CH3):
- 2-butene exhibits geometrical (cis-trans) isomerism because the double-bonded carbons have two different groups attached.
- Two isomers exist: cis-2-butene and trans-2-butene.
Therefore, there are 2 geometrical isomers.
