The most appropriate reagent to distinguish between acetaldehyde and formaldehyde is :
Fehling's solution
Tollen's reagent
Schiffs reagent
iodine in presence of base
D.
iodine in presence of base
Iodine in presence of base is used to detect presence of CH3CO group in compound.
Therefore, formaldehyde and acetaldehyde are distinguished by using I2 and base.
The conversion of acetophenone to acetanilide is best accomplished by using :
Beckmann rearrangement
Curtius rearrangement
Lassen rearrangement
Hofmann rearrangement
Formation of terylene is an example of:
condensation polymerisation
addition polymerisation
esterification
saponification
The dehydration of 2-methyl butanol with conc. H2SO4 gives :
2-methyl butene as major product
pentene
2-methyl but-2-ene as major product
2-methyl pent-2-ene
