Plastics Problem Unit Test

Front

What is the primary source of plastic waste?

Back

Packaging is the primary source of plastic waste.

Front

What type of chemical representation is a Skeletal Formula?

Back

A Skeletal Formula is a simplified representation of a molecule that shows the arrangement of atoms and bonds without depicting all the hydrogen atoms.

Front

Why is it important to examine functional groups on a molecule?

Back

Examining functional groups helps predict the properties of the substance, how it will react with other molecules, and identifies likely regions on the molecule that will attract other molecules.

Front

What is heptane?

Back

Heptane is a straight-chain alkane with seven carbon atoms, commonly used as a reference fuel in octane rating.

Front

What is propyne?

Back

Propyne is an alkyne hydrocarbon with the formula C3H4, characterized by a triple bond between two carbon atoms.

Front

Define 'polymer'.

Back

A polymer is a large molecule composed of repeating structural units (monomers) typically connected by covalent chemical bonds.

Front

What is the difference between a saturated and an unsaturated hydrocarbon?

Back

Saturated hydrocarbons contain only single bonds between carbon atoms, while unsaturated hydrocarbons contain one or more double or triple bonds.

Front

What is a functional group in organic chemistry?

Back

A functional group is a specific group of atoms within a molecule that is responsible for the characteristic chemical reactions of that molecule.

Front

Explain the term 'biodegradable plastic'.

Back

Biodegradable plastic is a type of plastic that can decompose naturally in the environment through the action of living organisms.

Front

What is the significance of the molecular formula?

Back

The molecular formula indicates the number and type of atoms in a molecule, providing essential information about its composition.
