Q 7.3

Q-7.3 ble have two organic compound der us say A and B. To find the Relationship between them, we have to name and check the chiselity and mirror images ere. compound (4) 33,4 Thichesoveplane compound (6) (2R, 35,5R ) 33,5 tki chloro reptane ce as ICH a 2* H 2R 3* 3R _*_ H 4s - 35 I I i I HH I o I I II IIII!! FJ-JJJg MC-H compound (1) and (b) non minor Image to each Hence they cannot be Enantiomers, They are not Supe imposable Hence they are Isomers and not identical, IN compound A, (2,3,4) In calbons are chiral, while in compound B, (2, 3,85 ) calbons are chiral. It means compound A and B have some molecular formula but bond connectivity is different, Herce It is constitutional Isomers. They are not conformers because in conformers bond connectivity and molecular formule is same Only bond angle differs heile A2 B are not ,

Both compounds have same molecular formula hence they are isomers, but they have different different carbon numbers are Cheral centres. Since here bond connectivity for both compounds are different hence they are Constitution Isomers. option (B ) is correct.
