Concept explainers
(a)
Interpretation:
The Lewis structures for acetone have to be drawn.
Concept introduction:
Lewis structures are also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
(b)
Interpretation:
The geometry around the carbon atoms of two Lewis structures of acetone has to be determined.
Concept introduction:
Molecular geometry can be predicted from the structure by using the valence-shell Electron-pair repulsion (VSEPR) model.
- Count the number of valence electron pairs (bond pairs and lone pairs).
- Assume that the valence electron pairs form a structure that allows them to be as far away from each other as possible.
- If there are only two bond pair electrons, the molecule is linear.
- If there are three bond pair electrons, the molecule is shaped like a trigonal planar.
- If there are four bond pair electrons, the molecule is shaped as a regular tetrahedral.
- Repulsion between lone pair-bond pair of electrons effect the geometry of molecules.
(c)
Interpretation:
The polar bonds in the Lewis structures of acetone have to be determined.
Concept introduction:
Covalent bonds are formed by sharing of electrons between atoms.
The polarity of a bond is arises due to the difference in electronegativity of atoms present in that bonding.
