isomerism e Constitutional isomers ●-- those have the C2H6O: CH3OCH3 CH3CH2OH C3H6O: CH2=CHOCH3 CH2=CHCH2OH same molecular formula CH3C(OH=CH2 CH3 CH=CHOH but vary in the CH3COCH3 CH3CH2CHO bonding attachments H3C of atoms OH
Isomerism Constitutional isomers ---- those have the same molecular formula but vary in the bonding attachments of atoms C2H6O: CH3OCH3 CH3CH2OH C3H6O: CH2=CHOCH3 CH2=CHCH2OH CH3C(OH)=CH2 CH3CH=CHOH CH3COCH3 CH3CH2CHO OH O O H3C
isomerism e Stereoisomers CHaCHECHOH OH with same bonding C=C attachments of atoms CH 3 OH CH but different Hac spatial orientations CH3 CH3 O
