The silver salt of a fatty acid on refluxing with an alkyl alide gives an
acid
ester
ether
amine
A compound A has a molecular formula C2Cl3OH. It reduces Fehling's solution and on oxidation, gives a monocarboxylic acid B. A can be obtained by the action of chlorine on ethyl alcohol. A is :
chloroform
chloral
methyl chloride
monochloroacetic acid
B.
chloral
Molecular formula of A = C2Cl3OH
As A reduces Fehling's solution and on oxidation gives a monocarboxylic acid B. It means A must be an aldehyde.
CCl3
This is further confirmed by the reaction:
C2H5OH + Cl2 CH3CHO CCl3CHO
A = Chloral [CCl3CHO]
The reaction in which phenol differs from alcohol is:
it undergoes esterification with carboxylic acid
it reacts with ammonia
it forms yellow crystals of iodoform
it liberates H2 with Na metal
An organic compound A containing C, H and O has a pleasant odour with boiling point of 78°C. On boiling A with concentrated H2SO4, a colourless gas is produced which decolourises bromine water and alkaline KMnO4. The organic liquid A is:
C2H5Cl
C2H5COOCH3
C2H5OH
C2H6
The catalyst used in the preparation of an alkyl chloride by the action of dry HCl on an alcohol is:
anhydrous AlCl3
FeCl3
anyhydrous ZnCl2
Cu
