When addition polymerisation of ethene takes place in a hydrocarbon solvent in the presence of ziegler-Natta catalyst, it forms:
LDP
HDP
Polyacrylnitrile
Teflon
The correct order of reactivity of phenyl Magnesium bromide with the following compound is:
(II)> (III)> (I)
(I)> (III)> (II)
(II)> (I)> (III)
(I)> (II)> (III)
Under basic condition which one suffers elimination the most?
(CH3)3CCI
(CH3)2CHCH2CI
CH3CH2CHCICH3
CH3CH2CH2CH2CI
The correct order of basicity of:
A> B > C > D
D > C>A> B
B > D > C > A
D>A> B > C
D.
D>A> B > C
Electron with drawing groups result in decreased basicity while electron releasing groups increases the basicity.
Thus, the order of basic character is
D > A > B > C.
