Consider the following reaction-
C2H5Cl + AgCN X (major)
Which one of the following statements is true for X ?
(I) It gives propionic acid on hydrolysis.
(II) It has an ester functional group.
(III) It has a nitrogen linked to ethyl carbon.
(IV) It has a cyanide group.
IV

I
The order of reactivity of phenol (I), nitrobenzene (II) and benzene (III) towards nitration is
(III) > (I) > (II)
(II) > (III) > (I)
(I) > (III) > (II)
(I) > (II) > (III)
The products formed, in the reaction of phenol with Br2 dissolved in CS2 at 0°C are
o-bromo, m-bromo and p-bromophenols
o-bromo and p-bromophenols
2,4,6-tribromo and 2,3,6-tribromophenols
2,4-dibromo and 2,6-dibromophenols
Identify phenacetin from the following-
D.
Phenacetin is a derivative of p-aminophenol and used as analgesic (pain killer). The main limitation of this drug is that it may act on red blood cells and thus may be harmful even in moderate dose.
C2H5OH + 4I2 + 3Na2CO3 → X + HCOONa + 5NaI + 3CO2 + 2H2O
In the above reaction, 'X' is
diodomethane
triodomethane
iodomethane
tetrariodomethane
