Organic Chemistry Chapter on Effects and Acidity

Study Notes

I Effect and Electron Displacement

The -I (inductive) effect results from the electron-withdrawing nature of substituents, which stabilize negative charges in a molecule.
The substituent -COOH shows the -I effect due to its electronegative characteristics.
Other groups such as -C2H5, -CHR2, and -CH2R exhibit weaker or no -I effects.

Displacement of Electrons

The displacement of electrons from a multiple bond when influenced by a reagent is known as the -M (mesomeric) effect.
Understanding the types of effects (I, M, E, R) is crucial in predicting molecular behaviors and stability.

Strength of Acids

Among the compounds listed (CICH2COOH, FCH2COOH, BrCH2COOH, ICH2COOH), the strongest acid is typically characterized by the most electronegative substituent, which enhances the acidity through stronger electron withdrawal.
The presence of fluorine in FCH2COOH makes it a significantly stronger acid compared to the others.

Homolytic Fission of C-C Bonds

Homolytic fission refers to the breaking of a bond where each atom retains one of the bonded electrons, resulting in free radical formation.
When C-C bonds undergo homolytic fission, it leads predominantly to the generation of free radicals, impacting the reactivity and stability of the given compounds.

Key Concepts in Organic Chemistry

Recognizing the inductive and mesomeric effects is essential for predicting how different groups influence reactivity and acidity in organic compounds.
The understanding of radical formation from bond fission is fundamental in organic reaction mechanisms.
