Chapter 9, Problem 9.101QP

(a)

Interpretation Introduction

Interpretation:

Lewis structure of CH3OH has to be drawn.

Concept Introduction:

Electron dot structure also known as Lewis dot structure represents the number of valence electrons of an atom or constituent atoms bonded in a molecule.  Each dot corresponds to one electron.

(a)

Expert Solution
Check Mark

Explanation of Solution

Total valence electrons in CH3OH is,

    (valence e- on C )(valence e- on H)+(valence e- on O) = 4+4(1)+6 = 14

Accordingly Lewis structure of CH3OH is drawn which shows 14 electrons in the molecule including bonding and non-bonding electrons.

Structure of ethyl group is,

General Chemistry, Chapter 9, Problem 9.101QP , additional homework tip  3

Tetraethyllead has molecular formula Pb(C2H5)4

Total valence electrons in Tetraethyllead is,

    (valence e on Pb )+ 8(valence e on C)+20(valence e on H) = 4+8(4)+20 = 56

Accordingly structure of Pb(C2H5)4 is drawn which shows 56 electrons in the molecule, including bonding and non-bonding electrons.

(e)

Expert Solution
Check Mark

Explanation of Solution

Total valence electrons in ClCH2CH2SCH2CH2Cl is,

    4(valence e on C )+ (valence e on S)+2(valence e on Cl)+8(valence e on H) = 4(4)+6+2(7)+8(1) = 16+6+14+8 = 44

Accordingly Lewis structure of ClCH2CH2SCH2CH2Cl is drawn which shows 44 electrons in the molecule, including bonding and non-bonding electrons.
