Question
The alkene that exhibits geometrical isomerism is
A.
propene
B.
2-methylpropene
C.
2-butene
D.
2-methyl-2-butene
Answer :
2-butene
Solution :
When two groups attached to a double bonded carbon atoms are same, the compound does not exhibit geometrical isomerism. Only 2-butene exhibits $$cis{\text{ - }}trans{\text{ }}$$ isomerism.
