Answer 1

- A molecule will be chiral if any of the carbon atoms of the molecule has a different groups attached to it. Actually there must be a different molecular envinonment The compound given here is that carbon will be called chinal carbon and the molecule Win be called chinal molcule we will be inspecting all of the carbons. with bare eyes, the first carbon that can be Chinal, we ty are starting inspect it In this combon me The combows with notation are have I same loqun environment so our inspected carbon (B) is not chinal. w Ang of A carbon TE LCM 1 - 0 cand E carbons as have same ennnmment (two ch atoms and once Canben) so, CA) is not chinal Now inspecting 'c carbon CH It has two it atoms. So, 1. not chinal

for D carbon ecin HO," It has two hydrogen atoms affached So, not chinal An Now for E carbon EL KE! These have two hydrogens attached to it so, not chiral Die to absence of any chiral Carbon, ..this compound is achinal
