when you do an NMR spec of a compund with a double bond.
for example if i cut out a small part. and say the two hydrogen atoms are in different environments in the molecule so it causes two peaks
H(a)----C=C---H(b)
when you do the spectrum, will the hydrogen (a) effect hydrogen (b) and so cause the peak to split. or does it have no effect?
another question.
if 2 hydrogens are on the same carbon in a C=C double bond.
does the fact they cant rotate mean they have different environments therefore causing 2 different peaks
