Concept explainers
(a)
Interpretation:
The most polar bond of methanol should be identified and polarity described with symbols
Concept Introduction:
Polarity of any molecule depends on electronegativity of atoms that forms covalent bonds. Depending upon the difference in electronegativity of atoms, polar or nonpolar molecule is determined. Polar molecule has electronegativity between 0.5 and 1.4 whereas in nonpolar molecule, it is less than 0.5.

Answer to Problem 43P
In methanol, most polar bond is O-H bond with electronegativity difference of 1.4 and oxygen atom becomes partial negative charge atom whereas hydrogen becomes partial positive charge atom.
Explanation of Solution
Polar covalent bonds contains more atoms with high electronegativity and acquire more partial negative charge represented as delta minus
In methanol, most polar bond is O-H with electronegativity difference of 1.4 and oxygen atom becomes partial negative charge atom whereas hydrogen becomes partial positive charge atom.
C-O bond have 1.0 electronegativity but it is less polar when compare to O-H bond.
