will be:
(a) In some cases, constitutional isomers are chiral
(b) In every cases, a pair of enantiomers have a mirror-image relationship
(c) Mirror-image molecules are in all cases enantiomers
(d) If a compound has an enantiomer it must be chiral
(e) Every chiral compound has a diastereomer
(f) If a compound has a diastereomer it must be chiral
(g) Every molecule containing one or more asymmetric carbons is chiral
(h) Any molecule containing a stereocentre must be chiral
(i) Any molecule with a stereocentre must show stereoisomerism
(j) Some diastereomers are mirror images to each other
(k) Any chiral compound with a single asymmetric carbon must have a positive optical rotation if the compound has the R configuration.
(I) If a structure has no plane of symmetry it is chiral
(m) All chiral molecules have no plane of symmetry
(n) All asymmetric carbons are stereocentre
(o) Gauche form of n-butane is chiral however anti form is achiral
(p) Molecules with two or more identically substituted stereocenters may exists as meso stereoisomers
(q) A stereocentre can be tetrahedral or trigonal planer
(r) both are comformational diastereomers.
