Optical isomerism

A COZ COMPOUND IS NEITHER MESO (I.E. NO PLANE OF SYMMETRY)
AND IT HAS CHIRAL CENTRES....

YA AB IS RITE TOO... EVEN THE N ATOMAS ARE CHIRAL

(a) because is has non superimposable mirror image ans (for chirality at least one carbon should be chiral) it has chiral carbon atoms. it does not have a plane of symmetry that is clear. so no centre of symmetry. but there is an axis of symmetry

plane of symmetry is like a mirror.......just like meso compounds.......

axis of symmmetry is an axis about which after rotating the structure to some angle original structure is retrieved.....

centre of symmetry is point about which on equal distances identical groups are located.......

my language above is casual .........i will try to give scientific version asap......

here is the official version::::::::

Center of Symmetry

The center of symmetry i is a point in space such that if a line is drawn from any part (atom) of the molecule to that point and extended an equal distance beyond it, an analogous part (atom) will be encountered.

Plane of Symmetry

Planes, centers and alternating axes correspond to "symmetry operations of the second kind" or "improper operations" since they bring into coincidence the material point of an object with its mirror reflection.

A plane of symmetry is a reflection plane which brings into coincidence one point of the molecule with another one through the mirror reflection.

Axis of Symmetry

Symmetry axis C_n, also called n-fold axis, is an axis which rotates the object (molecule) around by 360°/n, such that the new position of an object is superimposable with the original one.

ya got it da the option c will never comes da

y not c??

skygirl the comp is also the cis form and cis structures does not contain point of symmetry while trans can have

:( din get you :(

pls exlain
