Answer: True
The requirement for hydrogen bonding between two molecules is that, atleast one molecule should contain a hydrogen attached to a highly electronegative atom (like F, O, N) and the other molecule should contain a highly electronegative atom.
CH3OH contains a hydrogen atom attached to a highly electronegative atom, namely, oxygen. There is partial positive charge on hydrogen of -OH group and partial negative charge on oxygen.
There are two lone pairs of electrons on oxygen atom in dimethyl ether (CH3OCH3) as well as on oxygen atom in methanol (CH3OH). High electronegativity of oxygen and presence of lone pairs of electrons facilitates hydrogen bonding between oxygen of dimethyl ether (CH3OCH3) and hydrogen of -OH group in methanol (CH3OH).
(Hydrogen bonding between two methanol molecules will be prevalent; there will be hydrogen bond between oxygen of one methanol molecule with hydrogen in -OH group of another methanol molecule.)
Representing CH3OCH3 as (CH3)2O , hydrogen bonding between the two molecules is illustrated below,
(CH3)2O.......H-O-CH3

Select true or false for each statement below. True False Electron states are described by orbits, which indicate exactly where an electron is located in an atom. True False The energy levels of all atoms except hydrogen are quantized. True False Electrons move in elliptical orbits around the nucleus of an atom. True False Atoms can gain energy by absorbing a photon. True False When atoms are in an excited state, they can release this energy by emitting light.
A single type of atom cannot form more than one kind of a chemical bond. In another word, the strength of a chemical bond is independent of the identities of the atoms involved. Group of answer choices True False
