An alkanol can be prepared by the reaction of an alkene with
concentrated tetraoxosulphate (VI) acid
bromine tetrachloroethane
aqueous potassium tetraoxomanganate (VII)
sodium hydroxide solution
Correct answer is A
An alkene reacts with conc. H\(_2\)SO\(_4\) to yield an alkyl hydrogen tetraoxosulphate (VI). The compound formed undergoes hydrolysis when boiled with water to yield an alcohol.
Which of the following substances would not produce ethanol when fermented?
Cane sugar
Glucose
Starch
Vinegar
Correct answer is D
Vinegar is a product from fermentation. It can be gotten from the fermentation of ethanol.
cracking
fermentation

reforming
Correct answer is A
In the reaction, a complex hydrocarbon is broken down into two simpler hydrocarbons. This is cracking.
The oxidation number of Fe in [Fe(CN)\(_6\)]\(^{3-}\) is
+3
+2
-2
-3
Correct answer is A
Let the oxidation number of Fe in the compound [Fe(CN)\(_6\)]\(^{3-}\) be x.
x + 6(-1) = -3
x - 6 = -3;
x = -3 + 6
x = +3
