4. a chemical reaction during which one functional group in a chemical compound is replaced by another functional group.
10. This free radical is most stable.
12. These are electron loving species.
15. Species having a carbon atom bearing positive charge.
17. It is a type of organic reaction in which two substituents are removed from a molecule in either a one- or two-step mechanism.
18. Hyperconjugation explain the stability of these hydrocarbons.
19. Electrically neutral group having unpaired electrons.
20. This carbon has maximum plus inductive effect.

1. It is the reaction of an enolizable ester with a strong base to give a β-ketoester.
3. reaction common in compounds that have unsaturated C-C bond, like double (alkene) and triple (alkyne) bonds.
5. In this fission the bond breaks in such a way that each of the bonded atoms gets one electron of the shared pair.
6. covalent compounds that exhibit inductive effect.
7. Number of hyperconjugating structure in ethyl carbonium ion.
8. This effect is of great importance in conjugated compounds.
9. This effect involves displacement of sigma electrons.
11. It is a temporary effect produced in presence of reagent only.
13. Negatively charged carbon is in sp3 state.
14. Example of group exhibiting plus R effect.
16. In this bond breaks in such a way that both the electrons remain with one of the atoms.
