Question

What is the chemical formula for ethanol, given its structural formula depicted as a carbon atom bonded above, below, and left to hydrogen, and to the right to a second carbon, which is in turn bonded to an oxygen; the oxygen is bonded to the right to hydrogen?

A) CH6O
B) C2H5O
C) C2H5O2
D) C2H6O

Answer 1

The chemical formula for ethanol, given the described structural formula, is C2H6O, which corresponds to answer choice D) C2H6O.

Step-by-step explanation:

The chemical formula for ethanol, based on the structural description provided, would be C2H6O. This is because the molecule consists of two carbon atoms, six hydrogen atoms, and one oxygen atom.

The hydrogen atoms are bonded to the carbon atoms, and one of the carbons is bonded to an oxygen atom which is then bonded to a hydrogen atom, forming a hydroxyl (OH) group on the end of the molecule. Therefore, the correct answer is D) C2H6O.
