Which mixture is immiscible?

Options

  1. AC ₅ H ₁₂+ Alcohol
  2. BAlcohol + Amine
  3. CH ₂ O + Alcohol
  4. DAlkane + Alkane

Correct answer

A. C ₅ H ₁₂+ Alcohol

Step-by-step solution

Polar compounds are soluble in polar solvents and non-polar compounds are soluble in non-polar solvents. i.e. Like dissolves like. (i) C ₅ H ₁₂ (non-polar) + Alcohol (polar) (ii) Alcohol (polar) + Amine (polar) (iii) H ₂ O (polar) + Alcohol (polar) (iv) Alkane (non-polar) + Alkane (non-polar) Thus, C ₅ H ₁₂ and alcohol mixture is immiscible.
