Hydrogen bonding occurs when a hydrogen atom is covalently bonded to an N, O, or F atom. A hydrogen bond is possible with only certain hydrogen-containing compounds. The hydrides of group 5A are NH3, PH3, AsH3, and SbH3. Hydrogen atom: H (g) 216.034: 217.998 ± 0.000: kJ/mol: 1.007940 ± 0.000070: 12385-13-6*0: Dimethylamine (CH3)2NH (g) 3.75 ... and the Resulting Impact on the Bond ...

Explanation: Yes, we could consider, (CH 3) 2 NH, as a polar compound, with a dipole moment greater than zero, because it has a tetrahedral electronic geometry and C-H and C-N bonds that are polar covalent, due to the difference between the ... |
- Nov 16, 2016 · Briefly explain your choice. (CH3)2NH or CH3CH2CH3 Answer: (CH3)2NH is more soluble in water since it can hydrogen bond with water. Alkanes are not capable of hydrogen bonding with water.

Trimethylamine is a tertiary amine that is ammonia in which each hydrogen atom is substituted by an methyl group. It has a role as a human xenobiotic metabolite and an Escherichia coli metabolite. It is a tertiary amine and a member of methylamines.2. polarity and possibility for hydrogen bonding: #3 is nonpolar; #4 is polar but cannot form hydrogen bonds; #2 is polar, but its hydrogen bonds will be weaker than those in an alcohol; #5 is a secondary alcohol, so will form fewer hydrogen bonds than its primary isomer 21)B 22)E 23)D 24)A 25)E 26)E 27)A 28)A 29)E 30)B 31)C 32)C 33)C 34)D 35)E ...
Comments . Transcription . Organic Chemistry secondary (CH3)2NH 7.4 tertiary (CH3)3N 3.5 We will need to look at this with some care to sort out the patterns and reasons. Concentrate first on the primary amines. Primary amines It is useful to compare the boiling point of methylamine, CH3NH2, with that of ethane, CH3CH3.
Only CH₃NH₂ and CH₃OH can have hydrogen bonds between other molecules of the same kind. To have hydrogen bonding, you need an N, O, or F atom in one molecule and an H attached to an N, O, or F atom in another molecule.

Others point to the ionic nature of the bonds in BF 3. Synthesis and handling. BF 3 is manufactured by the reaction of boron oxides with hydrogen fluoride: B 2 O 3 + 6 HF → 2 BF 3 + 3 H 2 O. Typically the HF is produced in situ from sulfuric acid and fluorite (CaF 2). Approximately 2300-4500 tonnes of boron trifluoride are produced every year. The predominant attractive force in (CH3)2NH is: hydrogen bonding. London dispersion forces attractions between molecules depends on what two factors? Molar mass and shape. ... Which one of these molecules can act as a hydrogen bond acceptor but not a donor? CH3-O-CH3.

The hydrogen bonding isn't as efficient as it is in, say, water, because there is a shortage of lone pairs. Some slightly positive hydrogen atoms won't be able to find a lone pair to hydrogen bond ...
