Attempt either (a) or (b) :
(a) A carbon compound 'P' of molecular formula C2H6O is found to be neutral when tested with red and blue litmus. A gas that burns with a pop sound is produced when sodium metal reacts with compound 'P'.
(i) Identify the compound 'P'.
(ii) The carbon compound 'P' is heated with conc. H2SO4 at 443 K to produce compound 'Q'.
(I) Write the chemical equation for the reaction.
(II) What is the role of conc. H2SO4 in this reaction ?
(iii) What is likely to be observed on heating compound 'P' with ethanoic acid with an acid as a catalyst ? Write the chemical equation for the reaction.
Solution
(a)
(i) P- Ethanol /C2H5OH / CH3CH2OH
(ii)
(I)
(II) Dehydrating agent / Catalyst
(iii)
• Sweet smelling compound/ester is formed.
•
OR
(b) (i) ( any other resonating structure)
(ii) Carbon cannot form C4+ cation because removal of four
electrons is energetically not possible. Carbon cannot form C4−
anion because nucleus with six protons cannot hold ten
electrons.
(iii) Covalent bond
(iv)
/
Ethanol is converted to Ethanoic Acid by adding Alkaline
KMnO4/Acidified K2Cr2O7 as oxidising agent.
