And
Which of the following sets of molecular ions does an alkyl bromide posses ?

Please explain 8) Which CaHoBr compound gives a triplet at approximately 3.5 ppm in the iHNMR spectrum? 9) Which of the following sets of molecular ions does an alkyl bromide possess? a. two molecular ions in a 2:1 ratio separated by two mass b, two molecular ions in a 1:1 ratio separated by two mass units three molecular ions in a 1:2:1 ratio separated by two mass units d. two molecular ions in a 3:1 ratio separated by two mass units

Explanation / Answer

8) splitting takes place according to n+1 rule. Where n is number of hydrogen's attachedto adjacent carbon atom.

For the formation of triplet adjacent carbon must have two hydrogens.

Onlycompound 1 has possibility to form triplet at 3.5 ppm.

Hence correct option is (a). 1

9) The correct option is (b)

Two moleculor ions in a 1:1 ratio separated by two mass units.

The molar mass two isotope if Br are nearly equal so. 1:1 ration
