Answer: Steam volatile and immiscible with water.
- A Highly polar and strongly ionic
- B Soluble in water and non-volatile
- C Steam volatile and immiscible with water
- D Thermally unstable coloured solids
Correct answer: C. Steam volatile and immiscible with water
Explanation: The compound must be volatile in steam and insoluble in water so it distils over at a temperature below its normal boiling point, avoiding decomposition.
Geometric (cis-trans) isomers of 1,2-dichloroethene differ only in the relative arrangement of groups across the rigid C=C double bond.
Concept context
General Organic Chemistry covers the rules behind all organic reactions. Covers inductive effect, resonance, hyperconjugation, types of reactions (substitution, addition, elimination), and isomerism including optical and geometric forms.
