Answer

  1. No, immiscible liquids are separated by separating funnel.

  2. Separation of liquids by this process is based on difference in boiling points of the two liquids.

  3. Water remains in flask 'X' after condensation.

  4. As water has a higher boiling point so it remains in flask 'X' after condensation and methyl alcohol having lower boiling point boils and is collected in receiver after condensation.

  5. Fractionating column helps in condensation & separation of vapours.
