6:19 & 6:57 Sir, may I ask how did you get the ratio between the carbon and hydrogen? (6,4) & (9,1)
@ochemlounge
@ochemlounge Жыл бұрын
The m/z = 58 can have different constitutional isomers. Once we figure out the molecular formula and max number of carbons, there can be linear and branched isomers. The ratios stated as (6,4) are for the linear isomer butane with two methyl groups and two methylene groups. The (9,1) ratio is for the branched isomer 2-methlpropane that has three methyl groups and one methine.

yes, the solvent system should be THF, DMF is added in a catalytic amount (one or two drops) to activate oxalyl chloride.

Hi Matthew! Thanks for this, it's quite useful; for future reference, your audio needs to be cranked way up. People can always turn the volume down but we can't turn the volume up if it's recorded way too low. Fortunately, this has subtitles, but the spelling and word capture aren't always correct

probably because bromine is a bulky group [ hindrance with the hydrogen and carbon atoms] and you need to remove a double bond in order to add an extra bond to the carbon atom meaning no resonance so less stable so probably no
