Answer 1

Answes not Chemically non-equivalent Hydrogens Any group of Hydrogen present in a compound that can be interchanged by a mirros plane can be said to be chemically non- equi volent Hydrogens » Diosteriotopic protons are chemically non- equivalent and give different signal in NMR spectra. - For finding different type of protons . in molecule, we check ci, centre of symmetry = ci os č (ii, plone of a symmetry=o : () (2 - axis of sym met sy = c.
