stereoisomers
in the answer its given x=5 y=7 z=2
in the first one wont there be 5 structural and 3 stereoisomers so 8?
and in the 3rd one if S is already specified then wont there only 1 possible product?

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Fractional distillation does not separate stereoisomers since their physical properties are identical
As for the third one, how do you get an extra carbon? Is there a mistake in the print?
ohhh
Well, to be precise, optical isomers have the same physical properties. Geometrical isomerism is different, but that's not a thing for the first one.
hm seems so maybe they forgot to add methyl in the reactant
Yeah, so try adding that and doing it again.
alr thanks
hm then howd y be 7
im getiing 7 if we incude stereoisomers
@Opt
Huh. Yeah. That's inconsistent.
i guess the answer key is just wrong for this one ðŸ˜
That or we're cooked.
@Dexter take a look
If enantiomers banenge then the fractions will be same i guess
and diastereomers mein alag fractions aaenge
Very lengthy question goddamn
x= 5, since 5 structural isomers are possible and each will be obtained separately. There won't be any stereoisomers for each of these isomers due to the absence of restricted rotatory system and chiral centres. y=7 - I'll draw it out and send later. z=2, the config of cl at locant 3 is fixed so the other one can be R or S. there won't be structural isomers here since the IUPAC name has been provided. Also, each of these cases, i.e., the RS one and SS one will each have an enantiomer. But enantiomers cannot be separated by fractional distillation so we count them as one fraction
