Question

Which one of the following conformations of cyclohexane is chiral? (a) Boat (b) Twist boat(c) Rigid (d) Chair.

Answer 1

1. a) chair conformation is symmetrical                                                                                            b)boat is conformation is symmetrical                                                                                                                                       c)twist boat conformation =   it loses its symmetry due to twisting . we know that if a compound is symmetrical then it is not a chiral. Hence chair conformation and Boat conformations.      Both are achrial whereas twist boat is chiral .                        There is no such conformation as rigid so please make clear what exactly do you mean by rigid
