Reagents Flashcards
what does NaNH2 does to an alkene and what does it to alkyne
alkene converts to alkyne
the H on 3 bonded C is more acidic hence acid base reaction
HOCl in ionic form is? and what does it breaks into in first place!?
OH- and Cl+
it breaks into Cl+ first
which one is more soluble in diethyl ether? anyhdrous AlCl3 or Hydrious AlCl3
Anhydrous AlCl3 is more soluble in Diethyl ether as ether has electron pairs which can be acccomadated in the vacent orbitals of the Al(anyhydrous)
in hydrous one, the vacant orbitals are occupied by the electron pairs of H2O
What does H2 with Pd/Ni do to an alkene, acid halide, ketone,nitrile and nitro HC?!
And what can the above reagents cant reduce?
it cant reduce anhydride,carbo acid and ester
ketone is coneverted to alcohool
ntirle is converted to primary amine
what kind of addition does H2 with metals do>!
cis addition
How to make poisoned H2/Pd and what does it do and where else is it also used in the reaction(name reaction)
adding BaSO4 to H2/Pd makes it poison
it becomes mild reducing
it is also used in Rosenmund’s reaction
Whats lindlar’s reagent
Alkyne with liq NH3 forms and the type of GI formed is?
forms an alkene and a trans alkene is formed
Whats wilkinson’s catalyst
Sodium in alcohol is a reducing or oxidising agent?
reduces
R-CN on reduction forms?
primary amine
R-NC on reduction forms
secondary amine
R-CN with SnCl2/HCl/H2O forms?
and what is the reaction called?
Zn,Hg +HCl with Aldehyde/Ketone forms?!
Hydrocarbon
LiAlH4 is a reducing/oxidizing agent and which 3 compounds it cant reduce?
reducing agent
it cant reduce alkene,alkyne, and benzene
LiAlH4 with carbonyls forms?
alcohol(any carbonyl compound)
LiAlH4 with cinnamic compound forms?
LiAlH4 with cinnamic compounds can even reduce the alkene to alkane along with the extra grp reduction
LiAlH4 with ‘N’ Containing compounds forms?
amines
NaBH4 is oxidizing/Reducing agent and what 3 compounds can it reduce and what does it always reduce to?
reducing agent
it can reduce aldehyde, ketone, and acid halide to alcohol
DIBAL-H in aldehyde,ketone,acid halide forms?
What do DIBAL-H forms with nitriles followed by hydrolysis
What does DIBAL-H forms with Esters in cold medium
What does DIBAL-H forms with Esters iin hot medium
what is used to convert carbonyls to hydrocarbons if there is a
base sensitive grp in the compound
or an acid-sensitive grp in the compound
for base sensitive grp:- Clemmenson reduction(Zn-Hg, HCl)
for acid-sensitive grp:- wolf Kishner reduction ( NH2-NH2, KOH)
