• Newman


  Staggered

  
• Acidity

  Sp

  • Greatest nuclear exposure
  • Attract electron
  • Carbonion
• Acidity

  Sp3

  • Least ability to stabilize minus charge
  • The ability to attract electrons is least
  • Least Carbonion
• Staggered is more stable than eclipse.
• Sp = 50% S orbital
• Sp2 = 33% S orbital
• Sp3 = 25% S orbital
• Strong acid have stable conjugate base and fully dissociate.
• Weak acids only donate a little bit of protons.
• Weak acids are unstable conjugate bases that only partially ionise.
