Concept explainers
(a)
Interpretation:
The maximum number of hydrogen bonds that can form between an ethanal molecule and other ethanal molecules has to be determined.
Concept Introduction:
Due to the lone pair of electrons that is present on the oxygen in carbonyl group, hydrogen bonding is possible with water molecules and not with aldehyde molecules. Hydrogen bonds are weak force of attraction.
(b)
Interpretation:
The maximum number of hydrogen bonds that can form between an ethanal molecule and water molecules has to be determined.
Concept Introduction:
Aldehyde is an organic compound that has carbonyl carbon bonded to a hydrogen atom as its functional group. Carbonyl group is the nonpolar group.
Due to the lone pair of electrons that is present on the oxygen in carbonyl group, hydrogen bonding is possible with water molecules and not with aldehyde molecules. Hydrogen bonds are weak force of attraction.

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.
