Question 1
Compounds with the same molecular formula but different arrangements of atoms and different properties are called:
- AIsomers
- BHomologues
- CIsotopes
- DAllotropes
Show answerHide answer
Answer: A
This phenomenon is called isomerism.
Question 2
Constitutional isomers have the same molecular formula but different:
- ASpatial arrangement only
- BBond connectivity
- CNumber of atoms
- DMolar mass
Show answerHide answer
Answer: B
Constitutional isomers differ in how atoms are connected.
Question 3
Which of these is NOT a type of constitutional isomerism?
- AChain isomerism
- BPosition isomerism
- COptical isomerism
- DTautomerism
Show answerHide answer
Answer: C
The types are chain position functional metamerism and tautomerism; optical isomerism is stereoisomerism.
Question 4
Stereoisomers have the same bond connectivity but different:
- AMolecular formula
- BFunctional groups
- CAtomic number
- DSpatial orientation of atoms or groups
Show answerHide answer
Answer: D
They differ in configuration in space.
Question 5
Conformational isomers are interconverted by:
- ARotation about single bonds without breaking bonds
- BBreaking a pi bond
- CBreaking all bonds
- DAdding a catalyst
Show answerHide answer
Answer: A
Free rotation about a C-C single bond converts forms of butane.
