Now apply the n+1 rule from above to calculate the multiplicity, where n = the no. of Hs on neighboring carbons.
<quiz>
{For the left hand CH<sub>3</sub>, what is the multiplicity?
|type="()"}
- Zero
|| Wrong!  Remember it's n+1
+ 1
|| Correct!
- 2
|| Wrong!  Remember it's n+1
- 3
|| Wrong!  Remember it's n+1
- 4
|| Wrong!  Remember it's n+1

{What do you call a peak with that multiplicity?
|type="()"}
+ singlet
|| Correct!  Now go on to the '''[[Chem341:NMR workshop/Exercise 4c|next question]]'''.
- doublet
|| Wrong!  Look again...
- triplet
|| Wrong!  Look again...
- quartet
|| Wrong!  Look again...
- multiplet
|| Wrong!  Look again...
