Draw the structure of the: a) Aldehyde produced by treating ethanol with sulfuric acid and potassium permanganate b) Ketone produced by treating CH3CH(OH)CH3 with sulfuric acid and potassium permanganateExplanation / Answer
Solutions :-
Q1 a) Generally organic compounds are less dense than water.
b) The compound which would be more dense than water is the CH3CH2CH2Br
c) Majority of the organic compounds are immiscible with water.
d) Functional groups that are miscible with water are carboxylic acid (RCOOH), Alcohols (R-OH) and amines (R-NH2)
e) The intermolecular force that is hydrogen bonding between the the above listed functional groups helps them to become miscible with water.
f) Octanol is the alcohol that contains 8 carbons in the chain therefore it has both polar and non polar ends in the molecule. The long non polar chain of carbon prevents the octanol to become miscible with water.
Q2 balanced combustion equations are as follows
a) 2 CH3CH2CH2CH=CH2 +15 O2 ---- > 10 CO2 + 10 H2O
b) 2CH3CH2OCH3 + 9O2 ------ > 6CO2 + 8H2O
