In Friedel-Crafts alkylation,the other suitable substance used with $AlCl_3$ is..........

In $FCR$ (Friedel-Crafts Reaction),toluene can be prepared by which of the following?

Most common reactions of benzene (aromatic hydrocarbon) and its derivatives are

The compound shown below can be readily prepared by Friedel-Crafts reaction between

Consider the following reactions:
$C_2 H_2 \xrightarrow[500^{\circ}C]{\text{red hot iron tube}} A$
$A \xrightarrow[70^{\circ}C]{\text{conc. } HNO_3, \text{conc. } H_2 SO_4} B$
$B \xrightarrow{LiAlH_4} C_6 H_5-N=N-C_6 H_5$
$A$ and $B$ are:

Nitration is an example of aromatic electrophilic substitution reaction and its rate depends upon the group already present in the benzene ring. Out of benzene and phenol,which one is more easily nitrated?
