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
C.
cracking
The above reaction shows breaking of higher boiling, less volatile of hydrocarbons to lower hydrocarbons. Therefore, it is an example of cracking.

tetrahedral
non-planar
Alkali metals have high oxidation potential and hence, they behave as :
