1)in types of intermolecular forces= incr bp
a)vdw<d-d<b-b<ion-ion 2)incr SA = incr bp a)size--> bigger better b)shape-->linear best 3)incr polarizibility |

How to name alkanes?
|
1] Find longest C-C chain
a)if tied: most substituents b)if tied: sub w/ lowest # c)if tied: 2nd sub w/ lowest # d)if tied: sub comes 1st alphabetically 2]name substituents:--> #-prefix&name 3]put together: -sub. names/# + parent +suffix |

Acidity of protons?
|
1] Elemental: what element is H bonded to - incr in electronegativity = incr in acidity
2]Draw conjugate base - incr stability of conj base = incr in acidity a)Inductive: e- withdrawing groups in A = incr. stability b)Resonance: e- delocalization due to resonane = incr stability c)Hybridization: incr in s-character = incr in acidity |
