haloalkanes Flashcards
(11 cards)
what is a haloalkane
an organic molecule that contains at least one halogen atom (the functional group)
how to name haloalkenes ( if multiple halogens on one molecule)
alphabetical order
bromo
chloro
iodo
floro
are there dipoles on haloalkanes
C is delta positive and halogen is delta negative
define nucleophile
species that can donate a pair of electrons to an area of low electron density to form a new covalent bond
where do you draw the arrows in nucleophilic substitution
from lone pair to C with halogen
then to halogen
then species being substituted replaces halogen
what are the conditions required for nucleophilic substitution
aqueous sodium hydroxide
heating under reflux
why are haloalkanes more reactive than alkanes
haloalkanes have polar bonds where C (delta+) is more susceptible to nucleophilic attack
define hydrolysis
breaking down a molecule using water
how to turn a haloalkane into an alcohol
nucleophilic substitution using NaOH and heating under reflux
when the haloalkane has a stronger polar bond (C-Cl most)
what happens to the rate of hydrolysis
it increases
C-Cl bond breaks faster
the weaker the covalent polar bond, the faster the rate
the more polar the bond, the fater the rate
how do you determine if something is a nucleophile
needs one lone pair of electrons
