AP Inter 2nd Year Chemistry Important Reactions

In organic and inorganic chemistry, balanced chemical reactions with correct reaction conditions carry direct marks without deductions:

1. Reimer-Tiemann Reaction: Phenol reacts with chloroform in the presence of aqueous NaOH followed by acid hydrolysis to give salicylaldehyde.

2. Kolbe’s Reaction: Sodium phenoxide heated with carbon dioxide under pressure followed by acidification yields salicylic acid.

3. Cannizzaro Reaction: Aldehydes lacking an -hydrogen atom undergo self-oxidation and reduction in concentrated alkali to form an alcohol and a carboxylate salt.

5. Williamson Ether Synthesis: An alkyl halide reacts with sodium alkoxide to produce symmetrical or unsymmetrical ethers.

AP Inter 2nd Year Chemistry Important Definitions and Concepts

Clear, two-sentence conceptual clarity helps you write exact answers in the examination:

• Kohlrausch’s Law: The limiting molar conductivity of an electrolyte can be represented as the sum of the individual contributions of the anion and cation of the electrolyte.

• Hardy-Schulze Rule: The coagulating power of an electrolyte depends on the valency of the active ion; ions carrying higher opposite charges cause faster coagulation.

• Faraday’s First Law of Electrolysis: The amount of any substance deposited or liberated at any electrode during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte (m=zIt). 

• Lanthanide Contraction: The steady decrease in the atomic and ionic radii of the lanthanide elements with increasing atomic number due to poor shielding by 4f electrons.

• Enantiomers: Non-superimposable mirror image stereoisomers that rotate plane-polarized light in equal magnitudes but opposite directions.
