It has 8 valence electrons because the charge is -2.
Salt is usually formed during neutralization reactions,
that is the reaction of an acid and a base. This is illustrated as follows:
<span>HX + YOH --> XY
+ H2O</span>
where XY is the salt
From the given choices, the only pair of acid and base is:
<span>Vinegar and antacids</span>
If the totaling of bromine to cis-cinnamic acid uses the
same mechanism or device as the addition to trans-cinnamic acid, addition of
bromine only transpires on the top (syn) and not the bottommost face (anti). Therefore,
bromine added to cis-cinnamic only adds to the same face (syn addition) as a
result producing only threo dibromides.
