Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

For methyl group one signal (i.e a)as 3 of the Hydrogen attached to methyl carbon is same. For the carbon containing CH3 group there is also one H bonded to it which generates another signal (i.e indicated b) For position c there is two hydrogen which are same means enantiomeric in nature and gives another one signal… For position c,there is 2more hydrogen as well which are too enantiomeric giving rise to another signal in NMR spectroscopy.. So in total a,b,c and d i.e 4 signals are generated for methyl cyclopropane in NMR spectroscopy…
