[@amanuelyemane6553]

wow you explanations are awesome

[@darshanchhajer6455]

1:2:1 is the 3 ratios for bromine

[@Kishangehlot821]

good

[@chemroom5532]

Yes

[@anshupareek4638]

no one cares mf

[@zaramansoor7044]

6:26 how do you guess the fragment lost? i dont get how you randomly got H3CO

[@chemroom5532]

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

[@foshomustafa5000]

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

[@taaha8664]

Shouldnt the last answer be C3H7+ ??

[@chemroom5532]

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

[@chemmy8062]

Is this all I have to learn for mass spectrometry or is there more?

[@chemroom5532]

Yes

[@naijinyawo8316]

May I know what exam series(year/component code) are these past papers from? Thank you

[@chemroom5532]

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

[@naijinyawo8316]

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

[@BigMacWaltuh]

@@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??
