The table lists the index of refraction for various substances at 20^(@)C for light with a wavelength of 589nm in a vacuum. Through which substance will light with a vacuum wavelength of 589nm travel with the greatest speed ? {:("Substance",,n),("Fused quartz",,1.458),("Ethyl alcohol",,1.362),("Crown glass",,1.520),("Carbon tetrachloride",,1.461),("Crystalline quartz",,1.544):}

A 'U' tube contains oil, carbon tetrachloride and water as shown in the figure. The density of oil is 0.8 "g cm"^(-3) and that of carbon tetrachloride is 1.6"g cm"^(-3) . If oil and water surfaces are at the same level, find the height of the water column.

A compound is soluble in conc. H_2SO_4 . It does not decolourise bromine in carbon tetrachloride but is oxidised by chromic abhydride in aqueous sulphuric acid with in two seconds, turning orange solution to blue, green and then opaque. The original compound is

Compound (A) C_(6)H_(12) gives a positive test with bromine in carbon tetrachloride. Reaction of (A) with alkaline KMnO_(4) yields only (B) which is the potassium salt of an acid. Write structure formulae and IUPAC name of (A) and (B).
