Choose the most appropriate answer from the options given below:
Choose the correct sequence of reagents in the conversion of 4-nitrotoluene to 2-bromotoluene.
Identify the product in the following reaction

Identify 'X' in the following reaction.

The given compound

is an example of _________.
(A) $\beta $-Elimination reaction
(B) Follows Zaitsev rule
(C) Dehydrohalogenation reaction
(D) Dehydration reaction

The product ‘C’ is




CH3CH2CH2Br + NaCN $ \to $ CH3CH2CH2CN + NaBr
This reaction will be the fastest in

The reaction will be most favourable if M happens to be

The mechanisms of reactions (i) and (ii) are respectively

the product 'X' is

C$-$X bond towards nucleophile in the following compounds is
R $-$ Br + Cl$-$ $\buildrel {DMF} \over \longrightarrow $ R$-$Cl + Br$-$
which one of the following has the highest relative rate?

Z in the above reaction sequence is
obtained by chlorination of n-butane will be
is faster than 






In second Cl–atom has positive charge and partial
double bond character with C of vinyl group, so it
is more tightly attracted towards the nucleus and it
does not get replaced by nucleophile in nucleophilic
substitution reaction.
Chlorination of n-butane takes place via free
radical formation.
