The model of ethanol has six hydrogens.
To determine the number of hydrogens in the model of ethanol, we can count the hydrogen atoms bonded to the carbon atoms.
Ethanol has two carbon atoms. Each carbon atom is connected to three other atoms: two hydrogen atoms and one oxygen atom. That means each carbon atom contributes two hydrogen atoms.
Multiplying this by the number of carbon atoms gives us the total number of hydrogen atoms in ethanol.
So, since ethanol has two carbon atoms, each contributing two hydrogen atoms, the total number of hydrogens in ethanol is 2 * 2 = 4 hydrogens.
Therefore, the model of ethanol shown in the image contains Four (4) hydrogens.
To determine the number of hydrogen atoms in the model of ethanol, we need to count the hydrogen atoms directly attached to the carbon atoms in the structure.
Ethanol has the molecular formula C2H6O. In the model, we can see two carbon atoms (C) present. Each carbon atom is bonded to three hydrogen atoms (H). Therefore, for each carbon atom, there are three hydrogen atoms attached.
Since ethanol has two carbon atoms, we need to multiply the number of hydrogen atoms attached to each carbon atom by the number of carbon atoms present:
3 (hydrogen atoms per carbon) x 2 (carbon atoms) = 6 hydrogen atoms
So, the correct answer is six (6) hydrogens.
