Irccd.instructure.com HEM 421 LEC Quiz: Mass Spec Quiz py WS key.odl: ARC Sp18 CHEM The parent ion resulting from ionization of 3-chlorohex-2-ene will have the electron stripped from the bond. True False D Question 4 1 pts Silicon has three isotopes, 28Si (922%), 29Si (47%), and 30Si (3.1%). Therefore, you would expect to see three equal peaks for the parent at M, M +1, and M +2 True False D Question 5 1 pts Tertiary radicals generally give fairly small peaks in a mass spectrum. True False F5 F7 8

Explanation / Answer

3) yes, pi bond will be formed due to the partial overlap of p orbitals so they would first go and followed by the sigma bonded electrons. Electrons in pi bonds are loosly bounded than sigma bond.

4) No, depending on the Abundance the intensity and the ratio depends.

5) No, teriary radicals are more stable than secondary and primary so their abundance will be more in the mass spectrum therefore terialt radilara gives gives longer peaks.

Thanks
