Among the compounds represented by the constitution
there are a total of 2 stereoisomers and both are optically active.
there are a total of 3 stereoisomers and all are optically active.
there are a total of 3 stereoisomers; two are optically active and one is an achiral meso form.
there are a total of 4 stereoisomers and all are optically active.
there are a total of 4 stereoisomers; two are optically active and two are achiral meso forms.
a.there are a total of 2 stereoisomers and both are optically active.
b.there are a total of 3 stereoisomers and all are optically active.
c.there are a total of 3 stereoisomers; two are optically active and one is an achiral meso form.
d.there are a total of 4 stereoisomers and all are optically active.
e.there are a total of 4 stereoisomers; two are optically active and two are achiral meso forms.
Explanation / Answer
reson= If so, can they have E/Z (or cis/trans) forms. For two forms to exist around a double bond, the two things attached to each end of that C=C must be different from each other. For example, C=C that has a C and an H on each of the C=C carbons can have E and Z forms. However, if it has 2 H's on one end and a C and a Cl on the other, the 2 H's are identical and no E/Z forms are possible. Each double bond having E and Z forms can give 2 stereoisomers, but they are (almost) always achiral so are not optically
