AS Level Chemistry Mass Spectrometry - M : M+1 peak & M : M+2 peaks 

When a certain mass is lost we have to guess, like loss of 45 units is -COOH, loss of 15 units is -CH3 etc

⁠@@chemroom5532do u have a table for this? Or something where every thing we need to memorize is there plsss?

good

Yes

no one cares mf

Yes indeed. I'll remove the Br that i wrote like silly.

Yes

These are from paper 4 A2 exams since it's newly moved from there to AS

Shouldn’t the answer for the ratio of three lines with higher mass number be 1:2:1? Could you clarify? Thanks

@@naijinyawo8316 i think it's 1:2:1 since there are two possibilities for the hybrid: Br79-B81 and Br81-Br79

@@chemroom5532 if I am in A2, should I revise this as AS concepts are tested in A2??
