Total number of plane of symmetry in all conformations of 1,2-dichloro of ethane
Options:
Answer:
B
Solution:
Consider each conformation of ClCH2-CH2Cl: the anti conformer has one plane of symmetry (containing the C-C bond and bisecting the Cl...C...Cl arrangement); the fully eclipsed conformer (Cl eclipsing Cl) has two planes; the gauche and the partially eclipsed conformers have none. Total = 1 + 2 = 3.
