Question

number of chiral carbon in (M) \(= x\)


Number of Geometrical isomers in (N) \(= y\)

The value of \(\dfrac{y}{x}\) is:
(N)
(N)

• A. 5
• B. 1
• C. 7
• D. 3

Answer 1

The correct option is B 1

Chiral center is a tetrahedral atom in a molecule bonded with four different groups.


Number of chiral center in M, $x=6$


Possible arrangements around the double bond and the ring in N are as follows:
(i) Trans, Trans, Trans
(ii) Trans, Trans, Cis
(iii) Cis, Trans, Cis
(iv) Cis, Cis, Cis
(v) Cis, Cis, Trans
(vi) Trans, Cis, Trans
So number of geometrical isomers in N, $y=6$
$\therefore \frac{y}{x}=1$
