How many NMR signals are in Bromobutane?
The 9 hydrogen atoms (protons) of 2-bromobutane occupy 4 different chemical environments so that the low resolution NMR spectra should show 4 principal resonance peaks of different H-1 NMR chemical shifts (diagram above for 2-bromobutane).
How many peaks would be found in each signal of 1 Bromobutane?
4 peaks
Results are that there is 1 unique peak for each unique C in the structure. e.g. 1-bromobutane would show 4 peaks; 1-bromo-2-methylpropane would show 3 peaks.
What are equivalent hydrogens in NMR?
Equivalent hydrogens are H -atoms that are completely interchangeable as to their role in the molecule. So you can say that the hydrogens in the CH3 -group are equivalent, but the one in the OH -group is different.
What is the molecular weight of 2-bromobutane?
2-Bromobutane PubChem CID 6554 Synonyms 2-Bromobutane 78-76-2 SEC-BUTYL BROMIDE Molecular Weight 137.02 Date s Modify 2021-08-28 Create 2005-03-26
Which is the correct flash point for bromobutane?
MPPPKRYCTPRNTB-UHFFFAOYSA-N Computed by InChI 1.0.6 (PubChem release 2021.05.07) Computed by OEChem 2.3.0 (PubChem release 2021.05.07) 1-bromobutane appears as a clear colorless liquid. Flash point 65°F. Denser than water and insoluble in water. Vapors heavier than air. Colorless to pale straw-colored liquid 214 °F at 760 mm Hg (USCG, 1999)
What is the Koc of 1-bromobutane?
Using a structure estimation method based on molecular connectivity indices(1), the Koc of 1-bromobutane can be estimated to be 80(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-bromobutane is expected to have high mobility in soil.
Where does bromobutane come from in drinking water?
DRINKING WATER: 1-Bromobutane has been qualitatively identified in drinking waters in the U.S. as of November 25, 1974 by the U.S. Environmental Protection Agency of Cincinnati, OH(1). It may be formed from the chlorination of finished water, not during prior purification steps (1).
