Which of the following statements is not correct regarding aniline?

4 / 45

Structurally biodegrdable detergent should contain

5 / 45

Read the following statements and choose the correct option

(i) The numerical value of the equilibrium constant for a reaction indicates the extent of the reaction.

(ii) An equilibrium constant give information about the rate at which the equilibrium is reached.

(iii) If Kc > 103, products predominate over reactants, i.e., if Kc is very large, the reaction proceeds nearly to completion.

(iv) If Kc < 10–3, reactants predominate over products, i.e., if Kc is very small, the reaction proceeds rarely.

6 / 45

Which of the following statements are correct ?

(i) Ionic product of water (Kw) = [H+] [OH] =10–14M2

(ii) At 298K [H+] = [OH] = 10–7

(iii) Kw does not depends upon temperature

8 / 45

Brine is electrolysed by using inert electrodes.The reaction at anode is ________.

9 / 45

Read the following statements carefully.

(i) According to a convention cell potential of hydrogen electrode (S.H.E.) is considered to be zero at all temperatures.

(ii) e.m.f. of the cell Pt(s)/H2(g, 1 bar)/H+ (aq, 1 M) || Zn2+ (aq,1M) / Zn is – 0.76. This negative value indicates that Zn2+ ion reduces less easily then Hions.

(iii) Copper does not dissolve in HCl but dissolves in HNO3 as in nitric acid it gets oxidised by nitrate ion.

(iv) Inert metals like Pt or Au are used in certain electrodes i.e., these metals does not participate in reaction but provide surface for oxidation and reduction reactions.
(v) Fluorine has the highest electrode potential thereby making it strongest oxidising agent whereas lithium with lowest electrode potential is the weakest oxidising and strongest reducing agent.
