化学的性質
化学的特性2-bromopentane is a colorless to yellow-colored liquid with a strong odor. It is an optically active compound because it contains an asymmetric carbon (chiral carbon). An asymmetric carbon is carbon atom that is attached to four different types of atoms or groups of atoms. In 2-Bromopentance, the central carbon atom is attached to four different types of atoms (CH2, CH3, Br, H), hence it is an optically active compound.
