Which of the following is correct ?
If a compound has a diastereomer, it must be chiral
If a compound has chiral centres, it must be chiral
If a mirror image of a meso compound is its enantiomer
If a compound has enantiomer , it must be chiral
Meso compound have a mirrior image which is identical to itself. Compouns with chiral centers may be meso. Enantiomers are stereoisomers which which are non super imposable mirrion image of each other.
Cis - treams isomers are diastereomers which may not be Chiral
Hence, the court answer is option (4)
