QUESTION: 1

### Which of the following compounds will exhibit cis-trans isomerism?

Solution:
There will be 6 isomers possible for this formula.
take two halogens on any one of doubly bonded carbon and u would have three possible combination.
For each of this three structure each one will have cis and trans structures and so total 6.
QUESTION: 2

### Which of the following compounds exhibits stereoisomerism?              [JEE 2002(Scr.)]

Solution:
Since the compounds are optically active, it exhibits stereoisomerism.
HOOC---CH---CH2---CH3
|
CH2
QUESTION: 3

### In the given conformation, if C2 is rotated about C2 - C3 bond anticlockwise by an angle of 120° then the conformational obtained is                  [JEE 2004(Scr.)] Solution: When you rotate 120 degrees of c3 carbon then c1 when the carbon-rich position of C3 carbon atom. then this form is more stable because angle atoms are maximum. this process is known as gauche process angle between two atoms is 60 degree.

QUESTION: 13

Which of the following molecules in pure from is (are) unstable at room temperature         [JEE 2012]

Solution: (B) Eyclobutadiene follow Huckel's criteria for anti-aromaticity, hence unstable. (C) Follows Huckel's criteria for antiaromaticity, hence, unstable.
*Multiple options can be correct
QUESTION: 14

Which of the given statement(s) about N, O, P and Q with respect to M is (are) correct?     [JEE 2012]  Solution:

Fischer Projections of the molecules: It is clear that

M and N are non–mirror image stereoisomers.

M and O are the same molecules i.e. Identical

M and P are the non-superimposable mirror images of hence they are enantiomers.

N and Q are identical

M and Q are also  are non–mirror image stereoisomers i.e  diasteriomers.

Hence A, B and C are the correct statements.
