Meso compounds do not show optical activity because
1 they do not contain chiral carbon atoms
2 they have non-superimposable mirror images
3 they contain plane of symmetry
4 they do not contain plane of symmetry.
Explanation:
Meso compounds possess a plane of symmetry and is consequently optically inactive, eventhough chiral ' \(\mathrm{C}\) ' are present.

4 16
Explanation:
Structure of 1-bromo-2-methyl cyclobutane is This molecule cannot be divided into two equal halves, i.e., the molecule has no symmetry and \(\mathrm{n}\) is the number of asymmetric carbon atoms, then the number of \({\rm{d}}\) - and 1 - forms, \(\mathrm{a}=2^{\mathrm{n}}=2^{2}=4\) The number of meso forms, \({\rm{m = 0}}\) Total no.of optical isomers \(=\mathrm{a}+\mathrm{m}=4+0=4\)
