Stereochemistry of Reactions, quiz!
The fact that E-2-butene gives the
erythro
pair (above) only, makes the chlorohydrin formation:

stereoselective
stereospecific
The fact that Z-2-butene yields a different product (see below) makes the chlorohydrin formation:

stereoselective
stereospecific
Give the name and specification of stereocenters of the product (shown above) formed from Z-2-butene.
Why would water (or a chloride anion) attack the chloronium ion from the opposite direction?
Chloronium ion resulting from attack of chlorine on E-2-pentene
In the 2-pentene reaction (intermediate structure shown above) it is mentioned that water can attack either C2 or C3, that are not equivalent. Which carbon (if any) will be preferred? Why?

Hardly any difference
C2 preferred
C3 preferred
, because:
If we do the reaction with 1-pentene, which carbon (C1 or C2) will be preferred? Why?

Hardly any difference
C1 preferred
C2 preferred
, because:
