SOALAN MENGENAL PASTI FORMULA STRUKTUR SEBATIAN-SEBATIAN ORGANIK
Praujian:
An unsaturated organic compound A forms B when it reacts with hydrogen gas in a
presence of nickel. Compound A forms compound C when HBr is added. Compound B
forms compound C as well when bromine in tetrachloromethane is added to it. Compound
D is formed when compound A is added with concentrated sulphuric acid. Compounds F
and G are formed when ozone is added to compound A followed by hydrolysis with zinc.
The structural formulae of both F and G are given below:
F : CH3CHO G : CH3CH2C = O
CH2CH3
(a) Write the structural formulae of A, B, C and D. Write the equations for all reactions
involved. [8 m]
(b) Suggest a chemical test to show the presence of compound A. [2 m]
