Expert Solution
Step 1

In 1H nmr we get signal  due to proton which are magnetically and chemically non equivalent 

In nmr the splitting pattern is determined by the formula 2nI +1

Where I is nuclear spin and for hydrogen it is 1/2

n is number of equivalent hydrogen 

Similarly in 13 C mmr we get signal due to carbon  which are magnetically and chemically non equivalent 

If there is any symmetry element present present in the compound then number of signal will be lesser than actual number of carbon
