Polarity & Polymers (PreIB)

Front

What is the definition of a nonpolar molecule?

Back

A nonpolar molecule is a molecule that has an even distribution of electrical charge, resulting in no distinct positive or negative poles.

Front

What is an unsaturated molecule?

Back

An unsaturated molecule contains one or more double or triple bonds between carbon atoms, allowing for the potential to add more hydrogen atoms.

Front

What are synthetic polymers?

Back

Synthetic polymers are man-made polymers created through chemical processes, such as polymerization, and include materials like plastics.

Front

What is polyethylene?

Back

Polyethylene is a type of synthetic polymer made from the polymerization of ethylene monomers, commonly used in packaging and plastic products.

Front

What are natural polymers?

Back

Natural polymers are polymers that occur in nature and are produced by living organisms, such as proteins, nucleic acids, and polysaccharides.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have an uneven distribution of charge, leading to distinct positive and negative ends, while nonpolar molecules have an even charge distribution.

Front

What role do hydrogen bonds play in the properties of polar molecules?

Back

Hydrogen bonds are weak attractions between polar molecules that significantly influence their physical properties, such as boiling and melting points.

Front

What are the main types of polymers?

Back

The main types of polymers are natural polymers (e.g., proteins, nucleic acids) and synthetic polymers (e.g., plastics, nylon).

Front

How do the properties of synthetic polymers differ from natural polymers?

Back

Synthetic polymers can be engineered for specific properties, such as strength and flexibility, while natural polymers have properties determined by their biological functions.

Front

What is the significance of the degree of saturation in organic molecules?

Back

The degree of saturation affects the reactivity and physical properties of organic molecules; unsaturated molecules are generally more reactive than saturated ones.
