Cis / Z

Zaitsev's rule states that:


A) In electrophilic addition of an unsymmetrical reagent to an unsymmetrical alkene,the more positive portion of the reagent will become attached to the carbon of the double bond bearing the greater number of hydrogen atoms.
B) An equatorial substituent in cyclohexane results in a more stable conformation than if that substituent were axial.
C) E2 reactions occur only if the β\beta -hydrogen and leaving group can assume an anti-periplanar arrangement.
D) When a reaction forms an alkene,and several possibilities exist,the more (or most) stable isomer is the one which predominates.
E) The order of reactivity of alcohols in dehydration reactions is 3º > 2º > 1º.
