Which of the following statements correctly describes the Lewis dot structure of ethanol (C2H5OH)?
A
Ethanol has a central carbon atom bonded to three hydrogens and one oxygen, with no lone pairs on the oxygen.
B
Ethanol has a central oxygen atom bonded to one hydrogen and one carbon, with two lone pairs on the oxygen.
C
Ethanol has a linear structure with all atoms in a straight line and no lone pairs on any atom.
D
Ethanol has two carbon atoms each bonded to two hydrogens, and the oxygen atom is double-bonded to one carbon.
Verified step by step guidance1
Recall the molecular formula of ethanol, which is C2H5OH, indicating two carbon atoms, six hydrogen atoms, and one oxygen atom.
Understand the typical bonding patterns: carbon usually forms four single bonds, oxygen typically forms two bonds and has two lone pairs, and hydrogen forms one bond.
Analyze the structure of ethanol: one carbon atom is bonded to three hydrogens and the second carbon; the second carbon is bonded to two hydrogens and the oxygen atom.
Recognize that the oxygen atom in ethanol is bonded to one hydrogen (forming the hydroxyl group -OH) and one carbon, and it has two lone pairs of electrons.
Use this information to evaluate the given statements, identifying the one that correctly describes the Lewis dot structure of ethanol with the oxygen atom bonded to one hydrogen and one carbon, and having two lone pairs.
