2-chloro-4-methylanisole

Electron withdrawing group decreases the stability of carbocation.

Correct order of stability of carbocation is

Emulsion is a colloidal solution of liquid in liquid.

  $N{H}_4^{+}$  does not have vacant orbitals, therefore it cannot behave as electrophile.

t1/2 = [A]^1-n

for second order (n = 2) reaction : t1/2  is proportional to 1/ [A ]

More the number of ions in solution, more will be the specific conductance

 Ionic conductivity of H⁺ is more than that of Na+

Percentage Br =   $\frac{80*0.094}{188*0.16}*100=25\mathrm{\%}$

Acidic Nature : 

Correct order or atomic radii is

Tl > ln > Al > Ga > B

Li⁺ has the largest size in aqueous solution due to its high polarizing power.
