Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. 8

Sol. The geometrical-isomerism elements in the structure are : the two ring C=C bonds (a ten-membered ring accommodates both cis and trans double bonds), the C=C bond of the -CH=CH-CH₃ side chain, the C=C bond of the -CH=CH-CH₂CH₃ side chain, and the cis/trans relationship of the two side chains on the ring (the two adjacent ring carbons bearing them are stereogenic and differently substituted). Total number of independent elements n = 5, so

X = 2⁵ = 32

X/4 = 32/4 = 8
