\(0.01\) M aqueous solutions of following salts were prepared. Their conductivity values were measured at \(25°C\). Which of the following will possess highest conductivity at \(25°C\)?

Which of the following statements is incorrect with respect to the plot of molar conductivity (\(\Lambda_m\)) versus square root of concentration (\(c^{1/2}\)) for electrolytes in solution?

Answer the question on the basis of passage given below :
All transition elements display typical metallic properties like high melting point, boiling point, tensile strength, high malleability and ductility, luster, etc. Their metallic character increases down the group and elements of \(4 d\) and 5d series exhibit higher metallic characters. They show variable oxidation states and forms a number of coloured compounds due to the presence of unpaired electrons which shows d-d transitions and makes them paramagnetic.
The two strongest oxidising agents among the oxides will be :
A. \(MoO _3\)
B. \(CrO _3\)
C. \(Mn _2 O _7\)
D. \(WO _3\)
E. \(VO _2\)

Which of the statements given below are correct with reference to corrosion:
(A) Corrosion covers the surfaces of metallic objects with oxides or other salts.
(B) In corrosion, a metal is oxidised by the loss of electrons to oxygen and results in the formation of oxides.
(C) Rust is hydrated ferric oxide.
(D) A sacrificial electrode is used to save an object from corrosion.
Choose the correct answer from the options given below.

Read the passage carefully and answer the questions based on the passage:
Alcohols are versatile compounds as they can act as both nucleophile and electrophile. They undergo reactions based on cleavage of \(\mathrm{O}-\mathrm{H}\) and \(\mathrm{C}-\mathrm{O}\) bonds. The cleavage of \(\mathrm{O}-\mathrm{H}\) bond reflects the acidic character of alcohols. However they are weaker acids than water, phenol and carboxylic acids. Alkoxide ion formed by loss of proton from the OH group of alcohols reacts with water to form the corresponding conjugate acid - base pair. They act as Bronsted base due to presence of unshared electron pairs on oxygen.Both alcohols and phenol react with carboxylic acids, acid chlorides and anhydrides to form esters. The introduction of acetyl group in alcohols or phenol is known as acetylation. Alcohols react with hydrogen halides to form alkyl halides which form the basis of Lucas test. They also undergo acid catalyzed dehydration to form alkenes. Alcohols can be easily oxidized with variety of oxidizing agents. The nature of the product depends on the type of oxidizing agent and the nature of alcohol.
Oxidation of alcohols involves formation of carbon oxygen double bond with
