Splitting of a signal in a proton NMR spectrum tells us the number of chemically

Question

Splitting of a signal in a proton NMR spectrum tells us the number of chemically non-equivalent hydrogens in the immediate vicinity of the hydrogen giving the signal. Predict the number of lines exhibited by hydrogens at the labeled positions in a first-order NMR spectrum. (Make the approximation that all coupling constants are equal.) The number of lines exhibited by hydrogen(s) a is. The number of lines exhibited by hydrogens(s) b is. The number of lines exhibited by hydrogen(s) e is. The number of lines exhibited by hydrogen(s) a is. The number of lines exhibited by hydrogen(s) b is. The number of lines exhibited by hydiogen(s) e is.

Explanation / Answer

1) no of line excibited by hydrogen a is 3 acoordind tothe N+1 rule and a proton is attched to florine because of florine it will spitt furthr

no of line excibited by hydrogen b is 5

no of line excibited by hydrogen c is 3

2)

no of line excibited by hydrogen a is 4 acoordind tothe N+1 rule a

no of line excibited by hydrogen b is 2

no of line excibited by hydrogen c is 6
