Chemistry 7.1.1 Flashcards
Why can Carbon form a vast number of Compounds?
Because it can form strong Covalent Bonds with itself.
How many Covalent Bonds does a Carbon Atom always form?
4.
The Covalent Bonds a Carbon Atom form can be… (3)
Single, Double, Triple Bonds.
What is a ‘Functional Group’?
A specific Atom or group of Atoms which confer certain Physical and Chemical Properties onto the Molecule.
Organic Molecules are classified by the dominant ___ ___ on the Molecule.
Functional Group.
Define ‘Homologous Series’.
Organic Compounds with the same Functional Group, but a different number of Carbon Atoms.
Every time a Carbon Atom is added to the chain (in the Homologous Series), 2 ___ Atoms are also added. (in Alkanes).
Hydrogen.
What are the 3 types of Formulae that can be used to represent Organic Compounds? (4)
-General Formulae.
-Displayed Formulae.
-Molecular Formulae.
-Structural Formulae.
What is ‘General Formulae’?
Tells you the Composition of any member of a whole Homologous Series of Organic Compound.
What is ‘Displayed Formulae’? Give example.
Shows the Molecule and the Bonds & Atoms involved. Eg:
H H H H H-C-C-C-C-H H H H H
What is ‘Molecular Formulae’? Give example.
The Formula of the Molecule. Eg C4H8.
What is ‘Structural Formulae’? Give example.
Shows what Bonds are happening at each Carbon Atom. Eg CH3CH2CH2CH2CH3, or CH3(CH2)3CH3.
In a Homologous Series, each member has the same ___ Group.
Functional.
In a Homologous Series, each member has the same ___ Formula.
General.
In a Homologous Series, each member has similar ___ Properties.
Chemical.
