### Question 5Which of the following compounds have an asymmetric center?#### Options:**A)** - Structure: Propene - Description: The molecule has a double bond between the central carbon and one carbon attached to one hydrogen and one methyl group on each side.**B)** - Structure: 1,1-Dichloropropane - Description: The central carbon atom is bonded to two chlorine atoms, one hydrogen atom, and an ethyl group.**C)** - Structure: Isobutane - Description: A branched chain with a central carbon bonded to three other carbon atoms.**D)** - Structure: Cyclohexane - Description: A six-membered carbon ring with all single bonds between carbon atoms.**E)** - Structure: 2-Chloropentane - Description: A five-carbon chain with a chlorine atom bonded to the second carbon, which is also attached to a hydrogen, a methyl group, and an ethyl group.### ExplanationAn asymmetric center, also known as a chiral center, is a carbon atom that is bonded to four different groups. From the options given, only **E (2-Chloropentane)** has a carbon atom (the second carbon) which is bonded to four different groups: a chlorine, a hydrogen, a methyl group, and an ethyl group.

The chiral center or asymmetric center:If the molecule contains a carbon atom attached with four different types of atoms or groups known as the chiral or asymmetric center. The easiest identification of an asymmetric center is that molecule does not contain a plane of symmetry if the molecule has an asymmetric center.If the carbon atom attached to two same groups it will not be chiral because it has a plane of symmetry. Compound Plane of symmetry asymmetric center explanation yes no The double bond is substituted with the same pair of groups, hence it has a plane of symmetry. yes no The central carbon atom attached to two same chlorine atoms hence it is achiral. yes no The branched carbon atom is attached to the two same methyl group, hence it is achiral yes no cyclohexane molecule contains a plane of symmetry, hence it is achiral no yes the central carbon atom attached to four different groups hence it is asymmetric or chiral.The following compound has an asymmetric center: The asymmetric center is marked by a star:
