What is monosubstituted and disubstituted?
So monosubstituted means that 1 atom or substituent is replaced by another and disubstituted means that 2 atoms or substituents are replaced by 2 others. Of course, isomers are compounds with the same molecular formula but different structural formulas.
What makes an isomer more stable?
Cis isomers have substituents on the same side of the double bond, whereas trans isomers have substituents on opposite sides. The trans orientation is going to produce a more stable product due to steric hindrance, which is a physical limitation of the substituents.
What is the difference between stereoisomers and isomers?
Structural (constitutional) isomers have the same molecular formula but a different bonding arrangement among the atoms. Stereoisomers have identical molecular formulas and arrangements of atoms. They differ from each other only in the spatial orientation of groups in the molecule.
What is called isomerism?
isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties.
