Inductive Effect:
Inductive effect refers to the changes in the molecular structure of a molecule caused by the movement of electrons. When an atom or group of atoms in a molecule moves to a more electronegative atom, it can pull electrons away from the molecule, causing changes in its properties. For example, the presence of a carbon chain in an alkane can influence the properties of the molecule, as it can interact with the electrons in the carbon chain.
Electromeric Effect:
Electromeric effect is a non-orthoelectronic effect that involves the polarization of molecules caused by the movement of electrons. In an electromeric effect, the electrons are distributed differently throughout the molecule, leading to a change in molecular geometry. For example, the presence of a carbonyl group in an alkene can induce an electromeric effect, causing the carbon atoms in the carbonyl group to be more electron-rich than the carbon atoms in the alkene.
Resonance Effect:
Resonance effect is the ability of molecules to exist in multiple structural isomers. Isomers are molecules that have the same molecular formula but different structures. Resonance effect involves the delocalization of electrons in the molecule, which can lead to the formation of different resonance structures. For example, the benzene molecule can exist in several resonance structures, each with its own unique properties.
Hyperconjugation Effect:
Hyperconjugation effect is a non-bonding interaction that occurs when an atom or group of atoms in a molecule interacts with an atom or group of atoms in a different molecule. Hyperconjugation involves the sharing of electron density between the two molecules, which can lead to changes in their properties. For example, the alkene molecule can exhibit hyperconjugation interactions with the aromatic ring, which can affect its stability and reactivity
