Chapter 10, Problem 80E

Interpretation Introduction

Interpretation:

Chloromathanol isomer ${\text{ClCH}}_{\text{2}}\text{OH}$ should be sketched by using dash wedge symbolism with bond angles.

Concept introduction:

Whether the electron pairs are in chemical bonds (bond pairs) or lone pair, they do repel each other. The electrons are arranged in between the atoms of molecule such that the molecule will be stable with minimum repulsion.

Electron-group geometries and bond angles

• two electron groups: linear (180°)

• three electron groups: trigonal planar (120°)

• four electron groups: tetrahedral (109.5°)
