X and Y cn respectively be
Amongst the given options, the compound(s) in which all the atoms are in one plane in all the possible conformations (in any), is (are) [JEE 2011]
In Allene (C3H4), the type (s) of hybridisation of the carbon atoms is (are) [JEE 2012]
The number of optically active product obtained from the complete ozonolysis of the given compound is
Which of the following molecules in pure from is (are) unstable at room temperature [JEE 2012]
Which of the given statement(s) about N, O, P and Q with respect to M is (are) correct? [JEE 2012]
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.
