Which one of the following statement is false?
1 $\mathrm{R}$ and $\mathrm{S}$ configurations correspond to the enantiomers of an optically active compound
2 The process of converting an optically active compound into a racemate is called racemisation
3 A molecule containing a plane of symmetry can be optically active
4 Optical isomers that are not enantiomers are called diastereoisomers
5 All chiral objects are asymmetric
Explanation:
The false statement is (c) because if A Molecule containing plane of symmetry then it must be optically inactive and super imposable mirror image is formed example

Which one of the following is not an isomer of 3methylbut-1-yne?
1 2,3-dimethylbuta-1,3-diene
2 Pent-1-yne
3 Pent-2-yne
4 Penta-1, 3-diene
5 2-Methylbuta-1, 3-diene
Explanation:
Structure of 3-methyl but-1-yne It has total 5 C -atoms. But 2, 3-dimethyl buta-1, 3-diene has 6 atoms which is not possible to have an-isomer of this. So, (a) option is correct.
