Question 1
Most reactions of an organic compound take place at its:
- AFunctional group
- BAlkyl chain
- CCarbon skeleton
- DHydrogen atoms
Show answerHide answer
Answer: A
A functional group is the part of an organic compound where most of the reactions occur.
Question 2
Although millions of organic compounds are known the number of functional groups is:
- AVery large
- BOnly a handful
- CExactly one
- DZero
Show answerHide answer
Answer: B
There are only a handful of functional groups.
Question 3
Each functional group serves to define:
- AA single compound
- BAn element
- CA family of organic compounds
- DA solvent
Show answerHide answer
Answer: C
Each functional group defines a family of organic compounds.
Question 4
Functional groups play a central role in designing a synthesis because they enable chemists to:
- AAvoid all reactions
- BIncrease the mass of molecules
- CColour the compounds
- DPredict and control the reactions leading to the desired product
Show answerHide answer
Answer: D
Knowing the functional groups lets chemists predict and control reactions.
