A colourless organic liquid X of molecular formula C2H402 turns blue litmus to red. Another colourless organic liquid Y of molecular formula C2H60 has no action on any litmus but it is used as a nail polish remover. A yet another colourless organic liquid Z of molecular formula C2H6O has also no action on litmus but it is used in tincture of iodine.
(a) Name the liquid X. To which homologous series does it belong ? Give the name of another member of this homologous series.
(b) Name the liquid Y. To which homologous series does it belong ? Write the name of another member of this homologous series.
(c) Can you name an organic compound having the same molecular formula as liquid Y but which belongs to a different homologous series ? What is this homologous series ?
(d) Name the liquid Z. To which homologous series does it belong ? Write the name of another member of this homologous series.
