HYDROCARBONS

​Quarter 2 Week 6

​HYDROCARBONS

• ​is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H).

​

• ​ibig sabihin, ito ay mga ORGANIC COMPOUNDS na binubuo lamang ng carbon at hydrogen.

​THREE GROUPS OF HYDROCARBON

• ​Alkane - single bond

• ​Alkene - double bonds

• ​Alkyne - triple bonds

​ALKANE

• ​Tandaan na ang alkane ay may SINGLE BOND lang.

• ​Lahat ng alkane ay nagtatapos sa "ane" katulad ng methANE, ethANE, at propANE.

​ALKENE

• ​Tandaan na ang alkene ay may DOUBLE BONDS.

• ​Lahat ng alkene ay nagtatapos sa "ene" katulad ng ethENE, propENE, butENE, at pentadiENE.

​ALKYNE

• ​​Tandaan na ang alkyne ay may TRIPLE BONDS.

• ​Lahat ng alkyne ay nagtatapos sa "yne" katulad ng ethYNE, propYNE, butYNE, at pentaYNE.

• Ethane

• Methane

• Propene

• Propyne

Multiple Choice

Which hydrocarbon compound has a SINGLE bond in the molecule?

• Ethene

• Methane

• Propene

• Propyne

Multiple Choice

How many types of bonds are there in the following hydrocarbon compound?

• 1

• 2

• 3

• 4

Multiple Choice

The following compound is an example of:

• Alkane

• Alkene

• Alkyne

Multiple Choice

The following compound is an example of:

• Alkane

• Alkene

• Alkyne

​In summary....

• ​HYDROCARBONS are compounds that contain Hydrogen and Carbon atoms

• ​Three classifications of hydrocarbons: Alkane, Alkene, Alkyne

• ​Alkane - single bond (ends in "ane")

• ​Alekene - double bond (ends in "ene")

• ​Alkyne - triple bond (ends in "yne")
