The molecule shown are ch3 ci ih ci ich h cl ci h ch3 ch3 (b) diastereomers (a) enantiomers (c) constitutional isomers (d) non isomeris

Option a is correct in first structure both carbon have R and in second both have S

Enantiomers. here configuration of each carbon will be opposed. to find out relationship, assign R/S configuration and compaird it. if it is RR|SS then Enantiomer RR|RS then diaste...

Option A enantiomers Assign R and S configuration if it comes R,R on first isomers and S,S on second isomer and vice versa.... Or R,S or S,R in first isomer and S,R or R,S on seco...
