Organic Compounds

Question 1

What is organic compound?

Answer 1

All organic compounds can take oxygen, hydrogen atom, nitrogen atom or halogen atom

Question 2

What are called saturated compounds.

Answer 2

Compounds with only single bonds in their molecules are called saturated bonds.

Question 3

What are some example of saturated bonds?

Answer 3

Ethane and propane.

Question 4

What are unsaturated compounds?

Answer 4

Compounds containing double or triple bond ( in addition to single bonds) are called unsaturated compounds

Question 5

Example of unsaturated compounds?

Answer 5

Ethane and propane

Question 6

What are three types of structure?

Answer 6

Pentane is an unbranded hydrocarbon, methylbutance is a branded hydrocarbon, cyclopentane is a ring hydrocarbon

Question 7

What are molecular formula?

Answer 7

It show the number of each type of atom present in one molecule of a compound

Question 8

What is a display formula?

Answer 8

It show all the atom and bonds present in a molecule

Question 9

What is Functional groups?

Answer 9

Organic compound can be called according to the functional group they
contain

A functional group is a atom, a group of atoms or two carbon
atom with a double or tirple bond between them that is characteristic of a class of organic compound.

Example of functional group in organic compound are C = C- in alkene
- COOH in alkanoic acid

Different classes of organic compound have different functional groups.
The chemical properties of organic compound depend on the properties of the functional group or groups that they contain.

Question 10

What is homologous series?

Answer 10

A homologous series is a group of compounds that all contain the same functional groups. The member of the same homologous series.

Have the same functional group

Can be represented by a general formula for example each member of the alkane homologous series has the general formula Cn H2n + 2 is the number of carbon atom.

Differ from the member immediately before an after by CH2 group.

Have similar chemical properties ( because they have the same functional groups.

Slow gradual change in physical properties as the number of carbon atoms in the compound decreases.

Question 11

What are straight chain organic compound?

Answer 11

The first part of the name ( the stem) depends on the number of carbon atom present in the longest chain and of carbon atom ( see also) meth for one carbon atom, eth- for two carbon atom por- for these carbon atoms

The second part of the name ( the suffix) usually depends on the functional group.
