which of the following compounds are chiral? view available hint(s) ethane 2 - bromo - 2 - chloropropane…

Brief Explanations:

A chiral compound has a non - superimposable mirror image. A chiral carbon is a carbon atom bonded to four different groups. For the first question:

• Ethane has no chiral center as all carbon atoms have at least two identical groups.
• 2 - bromo - 2 - chloropropane has a carbon with two identical groups (the two methyl groups attached to the central carbon), so it is not chiral.
• Chloromethane has no chiral center as the carbon is bonded to three hydrogen atoms (identical groups).
• 2 - bromo - 2 - chlorobutane has a chiral carbon (the second carbon is bonded to a bromine, a chlorine, a methyl group and an ethyl group), so it is chiral.

For the second question:

• Dibromochloromethane has no chiral carbon as the carbon is bonded to two bromine atoms (identical groups).
• Chloroethane has no chiral carbon as none of the carbons are bonded to four different groups.
• 2 - butanol has a chiral carbon (the second carbon is bonded to a hydroxyl group, a hydrogen, a methyl group and an ethyl group).
• 1,1 - dichloroethane has no chiral carbon as the first carbon is bonded to two chlorine atoms and the second carbon has three hydrogen atoms.

Answer:

First question: 2 - bromo - 2 - chlorobutane Second question: 2 - butanol
