a molecule will exactly one chiral carbon is definitely going to be chiral
But here, we have two chiral carbons. In this case, the molecule may be chiral or chiral
As we can see here that there is plane of symmetry between both carbon, here the mirror image will be same as the molecule itself.
So, this is achiral
Answer: It is achiral because it is the same as its mirror image
Add Answer to:
Some molecules have more than one chiral carbon. In this case, the molecule itself may or...

3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms. Construct a model with four different colored balls about a carbon center. Construct another identical to the first and verify this by the superimposition test. Now remove the same colored balls, blue (C from...

PART 3: 2,3-BUTANEDIOL CH-CH(OH)-CH(OH)-CH, mirror images, not superimposable Build as many models of 2,3-butanediol as you can. First, attach two carbons with a single bond. To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14. What characteristic does one of these...

3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. 2 c) How many different isomers exist for methylcyclohexane (CyH34)? d)...

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...

Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...
