| will ammonia deprotonate ethylene? |
|
Definition
yup. ammonia pKa 33, ethylene pKa 25
it's the amide ions that will deprotonate the ethylene, not ammonia itself |
|
|
Term
pKas of:
ethane,
ethene,
ethylene |

Definition
15.9, 4.8, -1.9
The trend is due to the fact that the respective conjugate bases get more stable for compounds left to right bc of nr of O atoms. pretty cool |

|
Term
| why does ethane has higher pKa than ethene? |
|
Definition
| Upon the removal of H from ethane, the e will stay in an sp3 orbital, which is less stable than an sp2 orbital resulting from deprotonation of ethene. |
|
|
Term
| Are e in sp or sp2 orbitals lower in energy? |
|
Definition
| sp, because an sp orbital has more s character than an sp2 orbital. An s orbital is more stable bc s orbitals are closer to the nucleus and very low in energy |
