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

In alkaline earth metals cationic size increases down the groups, hence thermal stability of carbonates increases down the group. Therefore both assertion and reason are correct and reason is correct explanation of assertion.

$P=\frac{nRT}{V}=\frac{\left(1+2\right)*8.3*400}{4.0*10^{?3}}=24.9*10^{5}Pa$

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.

Micelles are not formed because it formed above CMC.
