Question
How many signals will be there in proton NMR of toluene?4321
Solution
The proton NMR of toluene will have 2 signals. Here's why:
-
Toluene is a compound with the formula C6H5CH3. It consists of a methyl group (-CH3) attached to a benzene ring.
-
In the context of NMR (Nuclear Magnetic Resonance), a 'signal' refers to a set of equivalent protons - protons in the same chemical environment that are indistinguishable from each other.
-
In toluene, there are two types of protons: the protons in the methyl group, and the protons in the benzene ring.
-
The three protons in the methyl group are all equivalent to each other, and so they give rise to one signal.
-
The five protons in the benzene ring are all equivalent to each other, and so they give rise to one signal.
-
Therefore, the proton NMR of toluene will have 2 signals.
