In H2C (ethylene or ethene), the carbon atom has no unshared (lone) pairs of electrons. Each carbon atom is bonded to two hydrogen atoms and is involved in a double bond with the other carbon, using all its valence electrons in bonding. Therefore, there are zero unshared pairs in H2C.

How many unshared pairs of electrons are in CO?
In carbon monoxide (CO), there are no unshared pairs of electrons. All the electrons are involved in bonding between carbon and oxygen.
Are there unshared pairs in CH3?
No, there are no lone pairs in a molecule of CH3. All atoms in CH3 are involved in bonding, so there are no unshared pairs of electrons on the carbon or hydrogen atoms.
What compound has two bonding pairs and two unshared pairs of electrons?
The compound with two bonding pairs and two unshared pairs of electrons is water (H₂O). In water, the oxygen atom forms two single bonds with two hydrogen atoms, while it also has two lone pairs of electrons. This arrangement leads to a bent molecular geometry due to the repulsion between the lone pairs, which affects the bond angles.
Why is the molecular geometry of water bent?
The molecular geometry of water is bent due to the presence of two lone pairs of electrons on the oxygen atom, which repel the bonded pairs, causing the molecule to form a bent shape. This is a result of the electron pairs arranging themselves in a way that minimizes repulsion and maximizes stability in the molecule.
Describe the role of each of the following in predicting molecular geometries a unshared electron pairs by double bonds?
In predicting molecular geometries, unshared electron pairs and double bonds influence the overall shape of a molecule. Unshared electron pairs tend to repel bonding pairs, causing distortions in the molecular geometry. Double bonds restrict rotation around the bond axis, affecting the spatial arrangement of the surrounding atoms and leading to a fixed geometry for the molecule.
