(a)

Summary Introduction

To determine: Whether a glove is chiral or nonchiral.

Introduction: Chirality is the phenomenon in which a molecule is not superimposable mirror image to each other. It is also known as asymmetric centers. A carbon atom attached with four different groups is chiral. The amino acid (except glycine) shows chirality because a central carbon atom is attached with four different groups. Glycine is a symmetrical or achiral because the central carbon is not attached with four different groups. A chiral molecule has handedness.
