Interpretation Introduction

To draw: The Lewis structures of the given compounds.

Interpretation: The Lewis structures of the given compounds are to be drawn.

Concept introduction: The Lewis structure shows the connectivity between atoms by identifying the lone pairs of electrons in a compound. Lewis structures are also called Lewis dot structures. The valence electrons around an atom are shown by dots. Bonds between atoms are shown by lines and the lone pair of electrons is shown by a pair of dots.

The rules to draw Lewis structure are given as,

  • Determine the electronegativity and the number of valence electrons contributed by each atom.
  • Generally lowest electronegativity atom is the central atom.
  • Write the skeleton structure of the molecule.
  • Use two valence electrons to form each bond in skeleton structure between the central and outer atoms.
  • Satisfy the octets of atoms by distributing remaining valence electrons as nonbonding electrons. It is usually best start with the outer atoms.

Interpretation Introduction

To show: The kinds of orbitals that overlap to form each bond in the given compounds.

Interpretation: The kinds of orbitals that overlap to form each bond in the given compounds are to be shown.

Concept introduction: In the sigma bond formation hybridized orbitals overlap with other hybridized or unhybridized orbitals. In the formation of pi bonds only unhybridized orbitals are involved.

3.

Interpretation Introduction

To determine: The approximate bond angles in the given compounds.

Interpretation: The approximate bond angles in the given compounds are to be stated.

Concept introduction: All the carbon atoms with single bond formation always arranged in tetrahedral manner. In tetrahedral arrangement the bond angles between the atoms is always 109°28'. This angle is thermodynamically more stable angle for tetrahedrally arranged atoms.

The actual bond angles in “sp”, “sp2” and “sp3” hybridization are 180°,120° and 109.5° respectively.

Construct the Lewis structures of the following compounds by combining the carbon atoms with the appropriate bonding patterns and the required number of hydrogen atoms. 2. a. hexane: CH,CH,CH,CH,CH,CH, b. 3-hexene: CH,CH,CH=CHCH,CH, c. 2-hexyne: CH,C=CCH,CH,CH, 3. There are three distinct bond angles formed in the four bonding patterns of carbon. What are they and in which bonding pattern(s) is each seen?
Determine if the structural formula below are acceptable Lewis structures for organic compounds. Point out the problems in cases where structure is invalid. CH3 CH;-N-CH-CH3 ČH3 A. This structure is correct because the valance of Nitrogen is complete. B. This is not a correct Lewis structure because Nitrogen can accommodate more atoms. C. This is not a correct Lewis structure because Nitrogen has a charge if it does not have three bonds. D. This is a correct Lewis structure.
