Organic Chemistry Fundamentals Questions

Multiple choice
  1. Benzisothiazolinone

  2. Benzisoxazole

  3. Tetracene

  4. Benzocaine

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Tetracene has the appearance of a pale orange powder. Tetracene is the four-ringed member of the series of acenes.It is a molecular organic semiconductor, used in organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs).

Multiple choice
  1. 2-Butoxyethanol

  2. Butene

  3. Butane

  4. 1,3-Butadiene

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Butene is an alkene with the formula C4H8. It is a colourless gas that is present in crude oil as a minor constituent in quantities that are too, small for viable extraction. It is ,therefore, obtained by catalytic cracking of long chain hydrocarbons left during refining of crude oil.

Multiple choice
  1. Acrylic acid

  2. Acryloyl chloride

  3. Adamantane

  4. Adenosine

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Adamantane is a colourless, crystalline chemical compound with a camphor-like odour. Adamantane molecules consist of three cyclohexane rings arranged in an armchair configuration. It is unique in that it is both rigid and virtually stress-free.

Multiple choice
  1. sesterterpenes

  2. triterpenes

  3. tetraterpenes

  4. polyterpenes

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Triterpenes consist of six isoprene units and have the molecular formula C30H48. The linear triterpene squalene, the major constituent of shark liver oil, is derived from the reductive coupling of two molecules of farnesyl pyrophosphate.

Multiple choice
  1. Adamantane

  2. Barbituric acid

  3. Acenaphthene

  4. Behenic acid

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Barbituric acid is an organic compound based on a pyrimidine heterocyclic skeleton. It is an odourless powder soluble in water. Barbituric acid is the parent compound of barbiturate drugs, although barbituric acid itself is not pharmacologically active.

Multiple choice
  1. Dimethylamine

  2. Methylamine

  3. Trimethylamine

  4. Methylhexanamine

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Methylamine is an organic compound with formula CH3NH2. This colourless gas is a derivative of ammonia, but with one H atom replaced by a methyl group. It is the simplest primary amine.

Multiple choice
  1. Enantiomers

  2. Diastereomers

  3. Configurational stereoisomer

  4. Conformers

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Enantiomers are two stereoisomers that are related to each other by a reflection. They are mirror images of each other, which are non-superimposable. Human hands are a macroscopic example of stereoisomerism.
