The belief that all living organisms are composed of cells.

The understanding that genetics determines the traits of an organism.

The notion that there is a vital life force or energy that distinguishes living from non-living matter.

What is the origin or history of organic chemistry?

It is traced when male extracted chemicals from plants and animals.

It is traced when male extracted chemicals from wood.

It is traced when male extracted chemicals from stone.

It is traced when male extracted chemicals from water.

What is the key step in radical polymerization of an alkene?

Removing of radicals (catalyst)

Which of the following statement is TRUE about Vitalism?

It is the idea that organic compounds could originate from living organisms.

It is the idea that inorganic compounds could originate from living organisms.

It is the idea that inorganic compounds could originate from dying organisms.

It is the idea that organic compounds could originate from nonliving organisms.

Which of the equation represents addition reaction?

CH3COOH + CH3OH → CH3COOCH3+ H2O

Why do most of our electrical cords are covered with polymetric materials?

because polymers are good electrical insulator

because polymers are good thermal insulator

because polymers have low coefficient of friction

because polymers have high chemical resistance

Which of the following is TRUE about inorganic compounds?

Inorganic compounds tend to be minerals which does not contain carbon-hydrogen bonds

Inorganic compounds are often flammable

Inorganic compounds contain carbon and support life.

Inorganic compounds are usually covalently linked to atoms of other elements

What is the product if you combine silver cyanate and ammonium chloride?

Solid silver chloride and Aqueous ammonium cyanate

What is the primary function of polymerization in chemistry and materials science?

To create large molecules (polymers) from smaller monomers

To generate heat and energy during chemical reactions

To break down complex polymers into simpler components

To facilitate the separation of mixtures through chromatography

What influence will advancements in nanotechnology have on our lives regarding organic and inorganic properties?

Advancements in nanotechnology can impact both organic and inorganic properties.

Organic and inorganic properties are unrelated to nanotechnology.

Advancements in nanotechnology will primarily impact organic properties.

There will be no influence of nanotechnology on organic or inorganic properties.

Can you design a compound name following IUPAC nomenclature without specifying the location of substituents?

No, the location of substituents must always be specified in the name.

Yes, but only when the substituent location is unknown.

Yes, but only for simple compounds with one substituent.

Yes, for any organic compound, regardless of complexity.

Can you see a possible solution to the challenge of naming a compound with multiple functional groups in the IUPAC nomenclature of organic compounds?

Prioritize the functional group closer to the end of the chain.

Use only the main functional group for naming.

Assign different prefixes to each functional group.

Ignore the less significant functional group during naming.

How many ways can you determine the parent chain (main carbon chain) in the IUPAC nomenclature of organic compounds?

One way, always follow the longest continuous carbon chain.

Four ways, choose the chain with the highest sum of carbon numbers.

Three ways, choose the chain with the lowest sum of carbon numbers.

Two ways, choose the chain with the most branches or the chain with the most substituents.
