MCQ
Benzene can react with
- A$B{r_2}$ water
- ✓$HN{O_3}$
- C${H_2}O$
- D$C{H_3}OH$
✓
Answer
Correct option: B.
$HN{O_3}$
b
$A.$ If double bonds were present then benzene would react in a similar way to alkenes, decolourising bromine water. However this does not happen as benzene doesn't react with bromine. Benzene cannot react in any other electrophilic addition reaction.
$A.$ If double bonds were present then benzene would react in a similar way to alkenes, decolourising bromine water. However this does not happen as benzene doesn't react with bromine. Benzene cannot react in any other electrophilic addition reaction.
$B.$ Benzene reacts with concentrated nitric acid at $323-333\, k$ in the presence of concentrated sulphuric acid to form nitrobenzene. This reaction is known as nitration of benzene
$C.$ Benzene is nonpolar and water is highly polar. If we add benzene to water, benzene will float on the top of the water with no apparent mixing.
$D.$ The alkylation reaction of benzene with methanol to produce toluene: $Y - C$ and $Y - C _{ cs }$ catalyst. The secondary reaction of toluene is difficult to be suppressed in benzene alkylation with methanol over conventional acidic zeolite catalysts. Moreover, the formation of coke yet remains a challenging problem.
Therefore on seen the all above option, we find $NO _3$ is best Suitable option.
