In Liebig's method for estimating carbon and hydrogen, the carbon content is calculated from the mass of:

Answer: CO₂ absorbed.

A H₂O collected
B N₂ liberated
C SO₂ formed
D CO₂ absorbed

Correct answer: D. CO₂ absorbed

Explanation: Carbon is oxidised to CO₂, absorbed in KOH; its mass gives carbon, while the H₂O absorbed in anhydrous CaCl₂ gives hydrogen.

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.
