Part a which of the following compounds can have stereoisomers? a) 2-pentene b) 2-chlorobutane c) 1-butene d) 2-methyl-1-butene part b which of the following compounds has both cis and trans isomers possible? a) 2-methyl-3-hexyne b) 1,2-dichloro-1-butene c) 2,3-dichloropentane d) 1,1-dibromopropene part c which of the following compounds are chiral? a) 2-bromo-2-chlorobutane b) ethane c) 2-bromo-2-chloropropane d) chloromethane part d which of the following compounds contains a chiral carbon molecule? a) chloroethane b) 1,1-dichloroethane c) dibromochloromethane d) 2-butanol

Part A: 2- Pentene and 2-chlorobutane have stereoisomers

Part B: Only 1,2-dichloro-1-butene has both cis and trans isomer

Part C: Only 2-bromo-2-chlorobutane is chiral

Part D: Only 2-butanol contains a chiral carbon

Explanation:

Stereoisomerism is a phenomenon where by compounds have the same molecular formular but different spatial arrangement

There are 2 types of Stereoisomerism

Part A: 2-pentene  has cis and trans isomer

            2-chlorobutane exhibit optical isomerism also. (option a and b)

Part B:  Only (option a) 1,2-dichloro-1-butene has cis and trans isomer

Part C: Only (option a) 2-bromo-2-chlorobutane has a chiral carbon. The chiral carbon is the 2nd carbon holding the Cl, Br, CH3 and C2H5 groups

Part D: Only (option D) 2-butanol has a chiral carbon. The 2nd carbon is the chiral carbon holding the H, OH, CH3 and C2H5 groups

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
