[MoooShuuu]

can someone explain how to do this for cyclo compounds?

 

[toothes]

look for symmetry

 

[joedat41]

i think it is 5 signals

 

[DiscoBalls]

nope, 4

 

[DiscoBalls]

well, 4 for H nmr, 5 for C nmr

 

[doc toothache]

i think it is 5 signals

The C4 and C6 hydrogens are equivalent and are split by the C-5 hydrogen into a doublet.

 

[joedat41]

yea 4 for H nmr and 5 for C nmr.

 

[MoooShuuu]

what is the splitting of the signals?

 

[AndyK]

what is the splitting of the signals?

2 singlets, one doublet, one triplet.

 

[rick4234]

yea 4 for H nmr and 5 for C nmr.

yes it is..

 

[klutzy1987]

well, 4 for H nmr, 5 for C nmr

This is correct.
