Which of the following best represents the correct Lewis structure for (ethynol)?
A
A cyclic structure with both carbons and the oxygen forming a three-membered ring, each carbon bonded to one hydrogen atom.
B
A structure with a double bond between the two carbon atoms, each carbon bonded to one hydrogen atom, and one carbon bonded to an oxygen atom via a double bond.
C
A linear structure with a triple bond between the two carbon atoms, one carbon bonded to an oxygen atom via a single bond, and each carbon bonded to one hydrogen atom.
D
A structure with a single bond between the two carbon atoms, each carbon bonded to two hydrogen atoms, and one carbon bonded to an oxygen atom via a single bond.

Identify the molecular formula given: C\_2H\_2O, which corresponds to ethynol, an alcohol derivative of acetylene (ethyne).
Recall that ethyne (C\_2H\_2) has a triple bond between the two carbon atoms, with each carbon bonded to one hydrogen atom.
Since the compound is ethynol, an -OH group (hydroxyl) must be attached to one of the carbons, replacing one hydrogen atom, and connected via a single bond to oxygen.
Draw the Lewis structure with a linear arrangement: a triple bond between the two carbons, one carbon bonded to a hydrogen atom, the other carbon bonded to a hydrogen atom and an oxygen atom via a single bond, and the oxygen bonded to a hydrogen atom (the hydroxyl group).
Verify that all atoms satisfy the octet rule (except hydrogen, which follows the duet rule) and that the total number of valence electrons matches the sum for C\_2H\_2O.
