General Chemistry

Acetaldehyde is an organic compound with the formula CH3​CHO. It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale industrially. The Lewis structure of a molecule represents the arrangement of atoms and the distribution of electrons in the molecule.

Step 1: Count Total Valence Electrons

To determine the Lewis structure, we first need to count the total number of valence electrons:

<ul>
	<li>Carbon (C) has 4 valence electrons.</li>
	<li>Hydrogen (H) has 1 valence electron.</li>
	<li>Oxygen (O) has 6 valence electrons.</li>
	<li>2 Carbons = 2&times;4= 8 electrons</li>
	<li>4 Hydrogens = 4&times;1= 4 electrons</li>
	<li>1 Oxygen = 1&times;6= 6 electrons</li>
	<li>Total valence electrons = 8 + 4 + 6 = 18 electrons</li>
</ul>

Step 2: Draw the Skeletal Structure

<ul>
	<li>Place the least electronegative atom in the center. In this case, carbon is less electronegative than oxygen, so it will be central.</li>
	<li>Connect the atoms with single bonds:</li>
</ul>

Step 3: Distribute Remaining Electrons

<ul>
	<li>After forming the initial single bonds (which account for 12 electrons: 6 bonds x 2 electrons/bond = 12 electrons), we have 6 electrons left.</li>
	<li>Place a double bond between the carbon and oxygen to account for 4 of the remaining electrons.</li>
	<li>This leaves 4 electrons.</li>
	<li>Place the remaining 4 electrons on the oxygen atom as lone pairs.</li>

	<li>The Lewis structure for acetaldehyde (CH3​CHO) consists of a central carbon atom bonded to three hydrogen atoms and another carbon atom.</li>
	<li>This second carbon atom is double-bonded to an oxygen atom.</li>
	<li>The oxygen atom also has two lone pairs of electrons.</li>
</ul>

Understanding the Lewis structure is crucial for predicting the molecule&#39;s shape, reactivity, and other chemical properties.
