Question

2)

polar protic solvent are ideal for sn1 reaction

polar protic solvent are polar and have Hydrogen attached to polar group

polar aprotic solvent are ideal for sn2 reaction

polar aprotic solvent are polar and do not have Hydrogen attached to polar group

A,B,C are polar aprotic solvent and they are ideal for SN2

D,E are polar protic solvent and they are ideal for SN1

3)

In chair form of cyclohexane

1,2 and 1,4 substitution, axial-axial or equatorial-equatorial are trans to each other.

1,2 and 1,4 substitution, axial-equatorial relation are cis-trans relation.

In 1,3 substitution axial-equatorial are trans to each other.

And axial-axial or equatorial-equatorial relation are cis-trans to each other.

Enatiomers : mirror image of original molecules

(all the stereocentres would be inverted in multistereocenter molecules)

Diastereomers : at least one stereocentre would be same as original molecules.

B) identical molecule

C) Enantiomers

D) Identical molecule

E) constitutional isomers

F) constitutional isomers

4)

A& B, A&C, A&F - Enantiomers

A& D, A&E - Diastereomers

Enantiomers - Non superimposible mirror images to each other

Diastereomers - Non superimposible non mirror images to each other
