Problem
When methanol (CH3OH) dissolves in liquid water, which molecular orientation of a water molecule relative to the methanol molecule is most favorable?
(a) Water molecules orient one of their hydrogens toward the oxygen atom of methanol’s –OH group, enabling hydrogen bonding
(b) The oxygen atom of a water molecule points toward the hydrogen of methanol’s –OH group to form a hydrogen bond
(c) Water molecules direct their hydrogens toward the methyl (CH3) group of methanol
(d) Because no specific intermolecular forces are present, water molecules adopt random orientations around methanol
