What is the hybridisation of carbon in ethene ()?
Answer and explanation
Correct answer: A.
- Step 1: Draw the Lewis structure of ethene (): each carbon atom forms two single bonds with hydrogen and one double bond () with the adjacent carbon.
- Step 2: Determine steric number: each carbon has electron domains ( bonds) and non-bonding lone pairs.
- Step 3: Three electron domains arrange in a trigonal planar geometry corresponding to hybridisation.
Answer
.
Why not the others: The alternative options (, , ) correspond to incorrect stoichiometric ratios, wrong reaction intermediates, or arithmetic evaluation errors.
