• optical

geometrical isomerism

optical isomerism

Multiple Choice

How to determine that a molecule exhibit cis-trans isomerism?

• Restricted rotation in a carbon-carbon single bond of alkenes

• Each carbon of a site of restricted rotation has 2 different atoms or groups attached to it

• Exist in cyclic compouds only

• Similar chemical properties

Multiple Choice

Multiple Choice

Which of the following statement is FALSEabout optical isomers?

• At least 1 asymmetrical chiral center

• Mirror images of each other

• Non superimposable

• carbon center bonded to 4 groups

Multiple Choice

Multiple Choice

Which structural formula represents an isomer?

Multiple Choice

The two Geometric isomers shown are called:

• Cis/trans 1,2 dichloroethane

• Cis/trans 1,2 dichloroethene

• Cis/trans 1,2 chloroethane

in organic reaction -mechanism, there are two ways covalent bond are broken

• homolytic fission

• heterolytic fission

homolytic fission

free radical substitution

heterolytic fission
