Question

For 2-bromo-3-chloropentane... finding ratios of molecular ion integrations of the compound listed

M+ value=

M+2 value=

M+4 value=

M+6 value=

Answer 1

Chlorine and bromine have two naturally occuring isomers. These isomers can easilily detected by mass spectrum. If molecule contains one chlorine and one bromine atom the ratio of different peaks can be calculated as follows.

There is no peak at m+6 mass, thus its intensity is zero.

Final answer:

m+ value = 3

m+2 value = 4

m+4 value = 1

m+6 value = 0
