QUESTION Which of the following compounds ivare chiralinemine the New projecte carefully perhaps deww them in as simple structures) CH Hic CH Н. H снен H H 2 only 1 and 2 only 2 and 3 1, 2 and 3

Answer 1

Answer is second option only 1 and 2

For a compound to be chiral,

• Atleast one chiral carbon should present in the compound
• There will be no axis or plane of symmetry.

Hence the compounds 1 and 2 are chiral due to the presence of a chiral carbon. But 3 is achiral, due to the absence of asymmetric carbon.
