isomerism _1.1

structural isomerism include

• chain isomerism

• position isomerism

• functional isomerism

the cis-trans isomerism must contian C=C .

• TRUE

• FALSE

a molecule that contains C=C must exist cis-trans isomerism

• FALSE

• TRUE

the molecule contains cis-trans isomerism because the C=C double bond is restricted to rotation

• TRUE

• FALSE

stereoisomerism include

• cis-trans (or geometrical) isomerism

• optical isomerism

a molecule that contains chiral centre must exist optical isomerism

• TRUE

• FALSE

optical isomers mean that exist two non-superimoposable mirror images

• TRUE

• FALSE

chiral centre: a ______ atom bonded with _______ different groups

• carbon , four

• hydrogen, two

• oxygen , four

• oxygen, two
