Name the gas evolved when ethanoic acid is added to sodium carbonate. How would you prove the presence of this gas?
What will you observe when dilute ethanoic acid and dilute hydrochloric acid are put on universal indicator paper, one by one? What does it show?
The substance which can produce brisk effervescence with baking soda solution is:
(a) ethanol
(b) vegetable oil
(c) vinegar
(d) soap solution(b) hydrocarbon ends directed towards the centre and ionic ends directed outwards
In a soap micelle, the soap molecules are arranged radially with the hydrocarbon ends, i.e. hydrophobic, directed towards the centre; and, ionic ends, i.e. hydrophilic, directed outwards.
An organic compound A (molecular formula C2H4O2) reacts with Na metal to form a compound B and evolves a gas which burns with a pop sound. Compound A on treatment with an alcohol C in the presence of a little of concentrated sulphuric acid forms a sweet-smelling compound D (molecular formula C3H6O2). Compound D on treatment with NaOH solution gives back B and C. Identify A, B, C and
