Question

"(a) Friedrich Wohler converted an inorganic compound into an organic compound in the laboratory.
(i) Give the name and formula of inorganic compound.
(ii) Write the name and formula of organic compound formed.
(b) Give the molecular formula of butane and mention the names of its two isomers. Name one fuel which contains both these isomers."

Answer 1

(a) i) Name of the organic compound formed in Ammonium cyanate and its formula is $NH_4 CNO$.

(ii) The inorganic compound is urea and it has the formula, $CO(NH_2 )_2$.

(b) Butane’s molecular formula is $C4H10$. Two of its isomers 2-methylpropane and n-butane.

Explanation:

(a) The vital force theory was disproved by Friedrich Wohler by conducting the test in which urea was prepared from the inorganic compound.  

(b) Butane is an alkane that has four carbon atoms. At room temperature, butane it a gas just like it is in atmospheric pressure.
