Question

$Cis-trans$ isomers generally:

• A. contain an asymmetric carbon atom
• B. rotate the plane of polarized light
• C. are enantiomorphs
• D. contain double bonded carbon atoms

Answer 1

Answer: (D)

contain double bonded carbon atoms

Answer 2

(i) $Cis-trans$ isomers contain double bonded carbon atoms.
(ii) Presence of asymmetric carbon atoms, enantiomorphs and ability to rotate plane polarised light are associated with optical isomers.
