Question

How many peaks do you expect to observe in the NMR signal of the CH proton of 2-methylpropane, (CH₃)₃CH? (answer is 10)

science chemistry

Answer 1

Answer #1

Number of peaks can be calculated by using formula

2nI + 1

Where I is the integral spin for H value of I is 1/2

And n is the number of neighbouring proton

In 2 -methyl propane

There are 9 neighbouring proton of CH

So the no. Of peaks will be

2*9*1/2 + 1

i.e. 9+1 = 10

Hope it will help you :)
