Match the following columns :

Answer

a-q,s ; b-q,s ; c-p,s ; d-q,r

Explanation

(a) 2-chiral centre, one-alkene which can show geometrical isomerism. `therefore` Stereoisomerism = 8
(b) 2-chiral centre , `therefore` stereoisomer `= 2 ^(2)=4`
( c) Copound is symmetrical and has even
`therefore a=2^(n-1)=2` (`alpha` = optically active compound)
`m=2^(n/2-1)=1`
Total steroisomer a+m=3
(d) Total chiral centre is one
`thereforea=2^(1)=2`
