Number of geometrical isomers of the compound CH₃-CH=CH-CH=C=CH-CH=CH-CH₃ are :
Options:
Answer:
D
Solution:
The two terminal CH=CH double bonds are each stereogenic : 2 x 2 = 4 combinations. The central C=C=C unit has an even number of cumulated double bonds and produces axial (optical) isomerism, which is not counted as geometrical isomerism here.
