HYDROGEN BONDING

• WHAT IS HYDROGEN BONDING?

  special form of dipole-dipole forces
• WHAT ARE THE CONDITIONS REQUIRED FOR HYDROGEN BONDING?

  a very electronegative atom with a lone pair of electrons covalently bonded to a hydrogen atom
• EXAMPLE OF A MOLECULE WITH HYDROGEN BONDS?

  water
• WHEN IS THE ONLY TIME HYDROGEN BONDING OCCURS?

  when a hydrogen atom directly binds to a N, O, F atom
• WHAT ARE WEAKER HYDROGEN BONDS OR COVALENT BONDS?

  hydrogen
• WHY IS THE WEAKNESS BETWEEN HYDROGEN BONDS IN COMPARISON TO COVALENT BONDS USEFUL?

  can be made/ broken in conditions where covalent bonds are unaffected
• WHAT IS THE CHARGE NORMALLY ON A HYDROGEN ATOM?

  delta positive (slightly)
