Hello people. it is chemistry time !! I am currently studying in UiTM PAlam, Foundation in science.
since I am in my sem break, I decided to do a little study on the subjects that I am going to learn in the 2nd semester. so here is the first chapter for sem 2. enjoy.

ORGANIC CHEMISTRY

REVIEW QUESTIONS

CLASSES OF ORGANIC COMPOUNDS
24.1 Explain why carbon is able to form so many more compounds than any other element?
ANSWER :
  • Because carbon atoms are able not only to form single, double and triple carbon-carbon bonds, but also to link up with each other in chains and ring structures.
  • Because carbon atoms can link up with other carbon atoms in straight and branched chains.

24.2 What is the difference between aliphatic and aromatic hydrocarbons ?
ANSWER : *KIV
  • Aliphatic hydrocarbons are divided into alkanes, alkenes and alkynes.
  • Aromatic hydrocarbons are Benzene.
ALIPHATIC HYDROCARBONS
 24.3 What do "saturated" and "unsaturated" mean when applied to hydrocarbons?
         Give examples of a saturated hydrocarbon and unsaturated hydrocarbon.
ANSWER :
  •  Saturated hydrocarbon contains the maximum number of hydrogen atoms that can bond with the number of carbon atoms present . Example : Alkanes
  • Unsaturated hydrocarbon are compounds with double or triple carbon-carbon bonds that enable them to add hydrogen atoms. Example : Alkenes
24.4 Give three sources of methane
ANSWER :
  • Termites
  • Sewage treatment processes
  • Anaerobic bacterial decomposition of vegetable matter under water
