Question 1

structural isomer

Answer 1

different compound having same molecular formula

Question 2

stereoisomers

Answer 2

same constitution, same formula but different spatial arrangement

are also configuration isomers which then split into geometric isomers and optical isomers

Question 3

conformational isomer

Answer 3

different arrangement of atoms from bond rotation

Question 4

configurational isomers

Answer 4

different compounds that can only change by breaking bonds

Question 5

enantimors

Answer 5

are non super impossible mirror images which have identical physical properties such as melting point boiling point , NMR nut the only exception is they rotate plain polarized light in qual but opposite directions

Question 6

polarimetry

Answer 6

plain polarized light

Question 7

resonance

Answer 7

electrons arrenged diffrently

Question 8

tautomer

Answer 8

atoms arranged differently

Question 9

constitutional isomers

Answer 9

different compound with same formulas or same molecular formula but different structural formula

Question 10

geometric isomers

Answer 10

cis or trans

Question 11

optical isomers

Answer 11

a molecule is chiral if it don’t have a plane of symmetry within
