The two optical isomers given below, namely are:
enantiomers
geometrical isomers
diastereomers
structural isomers
Which of the following statement is wrong ?
Using Lassaigne's test nitrogen and sulphur present in organic compound can be tested
Using Beilstein's test the presence of halogen in a compound can be tested.
In Lassaigne's filtrate the nitrogen present in a organic compound is converted into NaCN
In the estimation of carbon, an organic compound is heated with CaO in a combustion tube
Cis-trans isomers generally :
contain an asymmetric carbon atom
contain double bonded carbon atoms
rotate the plane of polarized light
are enantiomorphs
The following reaction represent,
C12H26 → C6H12 + C6H14
substitution
synthesis
cracking
polymerization
Hydrogen peroxide when added to a solution of potassium permanganate acidified with sulphuric acid:
forms water only
acts as an oxidizing agent
acts as a reducing agent
produces hydrogen
C.
acts as a reducing agent
The reaction of H2O2 with KMnO4 and H2SO4 is as follows:
+ 3H2SO4 + 5H2O2 → K2SO4 + + 8H2O + 5O2
Here, H2O2 acts as a reducing agent and if reduced to KMnO4 to Mn2+ ion.
The equilibrium molecular structure of hydrogen peroxide is :
Planar as given below
linear
tetrahedral
non-planar
Alkali metals have high oxidation potential and hence, they behave as :
oxidizing agents
Lewis bases
reducing agents
electrolytes

HCl and NaOH
CH3COOH and CH3COONa
KOH and CH3COOH
CH3COOH and NaCl
