Which of the following compounds can exhibit both geometrical isomerism and enantiomerism?
CH3CH2CCH3=CH—COOH
CH3—CHOH—COOH
CH3—CH=CH—CH3
CH3CH2—CHCH3—HC=CH—CH3
What will be the decreasing order of stability of following carbocations?
V >IV >III >II >I
I > II> III >IV >V
II >V > IV> I> II
I> II> III >V> IV
B.
I > II> III >IV >V
Structure (l) is aromatic.
Structure (II) shows -I effect due to presence of N(CH3)3 A group, which destabilises the carbocaton.
Structure (III) shows -I and R-effects, which destabilises the carbocaton more destabilises the carbocaton more.
Structure (IV) contains posItIve charge on its ring. Hence, It is less stable than structures I, II and III.
Structure (V) contains positive charge with triple bond, which has high tendency to gain electrons. Hence, it is least stable among all.
Decreasing order of stability
I > II > III > IV >V
