(a) Interpretation: Whether the hydrogen bonding occurred in a pure sample of dimethyl ether water or not should be predicted. Concept introduction: The type of dipole-dipole interaction between the highly electronegative element and a hydrogen atom (bonded to the electronegative atom) is known as hydrogen bonding. It is also formed between the unshared pair of electrons on the electronegative element (nearby) with a hydrogen atom.

Solution Summary: The author explains that hydrogen bonding occurs in a pure sample of dimethyl ether water.
Whether the hydrogen bonding occurred in a pure sample of dimethyl ether water or not should be predicted.

1. (A) Provide an example for each of the following:
(a) a molecule that only has dispersion forces as IMFs
(b) a molecule that has dispersion and dipolar IMFs
(c) a molecule that can experience hydrogen bonding
(B) Why does NH3 have a higher boiling point than BH3? To answer this question, draw out the Lewis structure for each molecule, and then draw out the VSEPR shape for each molecule.
Pick the correct pair of species that can form hydrogen bond with water.
(A)
CH,HCOOH
42
(В) F.HCOОН
(C) F,CH,OCH,
(D) Both (B) and (C)
Rubbing alcohol is the common name for 2-propanol (iso- propanol), C3H7OH. (a) Draw
the three-dimensional structure of the 2-propanol molecule and predict the geometry
around each carbon atom. (b) Is the 2-propanol molecule polar or nonpolar? (c) What
kinds of intermolecular attractive forces exist between the 2-propanol molecules? (d) The
isomer 1-propanol has the same molecular weight as 2-propanol, yet 2-propanol boils at
82.6 °C and 1-propanol boils at 97.2 °C. Explain the difference.
