(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.
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.
Interpretation Introduction
(b)
Interpretation:
The option that shows the hydrogen bonding between dimethyl ether and water should be predicted.

Pick the correct pair of species that can form hydrogen bond with water.
(A)

42
(В) F.HCOОН
(C) F,CH,OCH,
(D) Both (B) and (C)
Can Butane, Acetone, and Ethanol form a hydrogen bond with: (a) itself? (b) with water? Show where the hydrogen bond forms in a Lewis structure.
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.
