Options
- A. 2
- B. 3
- C. 4
- D. 6
Answer
A. 2
Step-by-step solution
Although CH _3 C = CH - CH = CH _2 has two double bond but one of them has two similar atoms (i.e. H -atom) therefore no geometrical isomerism is possible around the double bond. However each carbon atom of other double bond has two different atoms/groups and hence geometrical isomerism is possible around this double bond. Hence, only two geometrical isomers are possible.
