Chemistry Formulae for Physical Chemistry and Organic Conversions and Its Tricks

Physical chemistry and organic conversions are important topics in the NEET exam. Here are some important formulae and tricks to remember for these topics:

Physical Chemistry Formulae:
- Boyle's law: PV = constant
- Charles' law: V/T = constant
- Gay-Lussac's law: P/T = constant
- Combined gas law: PV/T = constant
- Ideal gas law: PV = nRT
- Van der Waals equation: (P + a(n/V)^2)(V - nb) = nRT
- Gibbs free energy: ΔG = ΔH - TΔS
- Nernst equation: E = E° - (RT/nF)lnQ
- Arrhenius equation: k = Ae^(-Ea/RT)

Organic Conversions and Their Tricks:
- Alcohol to alkene: Use a strong acid catalyst such as H2SO4 or H3PO4 and heat.
- Alkene to alcohol: Use a strong acid catalyst such as H2SO4 or H3PO4 and water.
- Alkane to alkene: Use a strong acid catalyst such as H2SO4 or H3PO4 and heat.
- Alkene to alkane: Use hydrogen gas and a metal catalyst such as Pt or Pd.
- Alkene to alkyl halide: Use a halogen such as Br2 or Cl2 and a radical initiator such as NBS.
- Alkyl halide to alcohol: Use NaOH or KOH and heat.
- Alcohol to aldehyde or ketone: Use PCC or Swern oxidation.
- Aldehyde/ketone to alcohol: Use LiAlH4 or NaBH4 reduction.
- Carboxylic acid to ester: Use an alcohol and a strong acid catalyst such as H2SO4 or H3PO4.
- Ester to carboxylic acid: Use a strong base such as NaOH or KOH and heat.

NEET Revision Notes:
NEET revision notes are important for students to review important topics before the exam. Here are some tips for creating effective NEET revision notes:
- Organize notes by topic or subject for easy review.
- Use bullet points and diagrams to make notes concise and easy to understand.
- Highlight important formulas, equations, and conversions.
- Use different colors or symbols to mark important information.
- Practice solving problems and questions related to each topic.
- Review notes regularly to reinforce information and identify areas that need more attention.
