X = Total number of possible geometrical isomers of octa-2,4,6-triene. The value of X/2 is :
Options:
Answer:
C
Solution:
Ans. (C) 3. Octa-2,4,6-triene, CH3(CH=CH)3CH3, has three stereogenic double bonds but the molecule is symmetric, so the 23 = 8 combinations reduce to 6 distinct isomers: (E,E,E), (Z,Z,Z), (E,Z,Z)=(Z,Z,E), (E,E,Z)=(Z,E,E), (E,Z,E) and (Z,E,Z). X = 6, so X/2 = 3.
