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

to make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 ml of water at 80 degrees celsius. when the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.
