Hinsberg method
Hofmann method
Wurtz reaction
Wurtz reaction
Amongst the following the most basic compound is
benzylamine
aniline
acetanilide
acetanilide
Which one the following does not have sp2 hybridized carbon?

Acetonitrile
Consider the acidity of the carboxylic acids
PhCOOH
p – NO2C6H4COOH
o – NO2C6H4COOH
o – NO2C6H4COOH
C.
o – NO2C6H4COOH
-NO2 group at any position shows electron withdrawing effect thus acid strength is increased. But o -nitro benzoate ion is stabilised by intramolecular H-bonding. Hence its acid strength is maximum. The effect is more at para position.
Which of the following compounds will be suitable for Kjeldah1’s method for nitrogen estimation?
The increasing order of basicity of the following compounds is:
(d) < (b) < (a) < (c)
(a) < (b) < (c) < (d)
(b) < (a) < (c) < (d)
(b) < (a) < (d) < (c)
The compound that does not produce nitrogen gas by the thermal decomposition is
(NH4)2SO4
Ba(N3)2
(NH4)2Cr2O7
NH4NO2
