Chlordiazepoxide is an example of tranquilizer.

In given following phenol and its derivaties only para-methyl phenol does not produce any colour with phthalic anhydride in the presence of conc. H₂SO₄.

The interaction energy of London forces ; $E\propto \frac{1}{r^6}orE\propto r^{-6}$ . Hence x = -6.

Intermediate : R – N = C = O (Isocyanate)

(C) Carbylamine reaction ->Test for primary amine.

  $R-N{H}_{2}orAr-N{H}_2+CHC{l}_3+3KOH\to R-NCorAr-NC+3KCl+3H_{2}O$                    

(D) Hoffmann orientation -> Anti saytzeff (Formation of less substituted alkene as major product)

Mass of organic compound = 0.45 gm

Mass of AgBr obtained = 0.36 gm

$\therefore MolesofAgBr=\frac{0.36}{188}$

$\therefore MassofBromine=\frac{0.36}{188}*80=0.1532gm$

$\therefore \mathrm{\%}Brincompound=\frac{0.1532}{0.45}*100=34.04\mathrm{\%}$                

Alitame is an artificial sweetener. It is a second generation of dipeptide sweetener. It is 200 times sweeter than sucrose.
