Solution
Across:
4.Constitutional Isomers
Cis and trans isomers are formed when the substituents are on opposite sides. These are
constitutional Isomers.
5. Levorotatory
When rotation of plane polarized light is towards the left, it is called levorotatory, and if to the
right then dextrorotatory.
6. Stereoisomers
Isomeric compounds with same connections but different spatial arrangements.
8. Stereocenters
11.Chiral
Have non-superimposible mirror images
13. Constitutional Isomers
Have different connectivities.
14. Raesmic Mixture
Have no optical activity due to external compensation by as equal amounts of + and -
enantiomers cancel each other.
15. Skeletol

2. These are skeletol isomers.
Down:
1. Diastereomers
They are stereoisomers which are not mirror images of each other or are not enantiomers.
2. Achiral
3. Dextrorotatory
7. Meso Compound
Show no optical rotation of plane polarized light due to internal compensation.
9. Functional
These are functional group isomers.
10. Enantiomers
12. Positional
Different position of functional groups will make them positional isomers.
