Least energetic conformation of cyclohexane is
1 chair conformation
2 boat conformation
3 $\mathrm{c} / \mathrm{s}$ conformation
4 E-Z form
Explanation:
Least energetic conformation of cyclohexane is chair conformation on because it is more stable

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 compound do not show optical activity although it has chiral center because it has plane of symmetry and super imposable mirror image. Example Mirror image with plane of symmetry
