CH3CD(I)CHD (Cl)
The increasing order of reactivity of the following compounds towards aromatic electrophilic substitution reaction is
D < A < C < B
B < C < A < D
D < B < A< C
A < B < C < D
Increasing rate of SN1 reaction in the following compounds is :
(B)<(A)<(C)<(D)
(A)<(B)<(D)<(C)
(B)<(A)<(D)<(C)
(A)<(B)<(C)<(D)
A.
(B)<(A)<(C)<(D)
Rate of SN1 reaction depends on stability of corbocation.
2-Phenylethylbromide when heated with NaOEt, elimination takes place. No deuterium exchange takes place when the reaction is carried out in C2H5OD solvent. The mechanism will be
E1 elimination
E2 elimination
E1 cB elimination
E2 or E1cB
