Question

which is the correct lewis structure for ethylene, c₂h₄?

Explanation:

In the Lewis - structure of ethylene ($C_2H_4$), each carbon atom has 4 valence electrons and each hydrogen atom has 1 valence electron. The two carbon atoms are double - bonded to each other, and each carbon is also bonded to two hydrogen atoms. There are no lone pairs on the carbon atoms in the correct Lewis - structure. Option A correctly represents the bonding in ethylene without any extra lone pairs or incorrect bond orders.

Answer:

A. A
