I am confused about the migratory aptitude of various groups in pinacole pinacolone rearrengement and otherwise, as there are many different orders for the same given in different places, especially about -Ph and -H. I would like to know if someone could reliably tell the order.

which of the following statements are true ?
1:rate of S​N2reaction decreses on increasing the dielectric constant of medium 
2: rate of aromatic SN2raction of aryl halides is governed only by inductive effect of substituent  attached on benzene ring 
3: rate of SN1 reaction does not depend on dielectric constant of the medium 
4: during SN 2 reaction of 2-chloroprpaoic acid with NaSH retetion of configuration takes place
