Question

assume that each object has no markings or printing. which of the following is Chirial?
unsharpened pencil
baseball bat
glove
hockey puck
glass

Answer 1

in order to be chiral --> it must have a stereocenter, that is, its mirror image must not fit correctly into th eoriginal object.

a)

unsharpened pencil --> this is symmetric, therefore, no chirality

b)

baseball batl --> this is symmetric, therefore, no chirality

c)

a glove is unique for right and left sides, therefore, choose chiral

d)

hockey puck is symmetric, it is not chiral

e)

glass is chiral, since it has different nonsymmetrical shape and organization
