Which molecules of life are built on carbon?

Explanations: answer key for all 10 questions

Q1: How many bonds does a carbon atom usually form?
Answer: Four
This lets carbon build chains, rings and complex 3D shapes.
Q2: What is the chemistry of carbon compounds called?
Answer: Organic chemistry
Once it meant only compounds from living things, but no longer.
Q3: What is the simplest hydrocarbon?
Answer: Methane
Methane is CH4, the main part of natural gas.
Q4: Who made urea from inorganic chemicals in 1828?
Answer: Friedrich Wöhler
This challenged the idea that organic chemicals needed a life force.
Q5: Which two forms of pure carbon are very different in hardness?
Answer: Diamond and graphite
Their atoms are arranged differently.
Q6: Gasoline is mainly a mixture of what?
Answer: Hydrocarbons
They release energy when burned.
Q7: Glucose contains carbon, hydrogen and which other element?
Answer: Oxygen
Its formula is C6H12O6.
Q8: Who imagined benzene's ring structure after dreaming of a snake biting its tail?
Answer: August Kekulé
Benzene has six carbon atoms in a ring.
Q9: Most plastics are made from what?
Answer: Carbon-based polymers
Many come from petroleum.
Q10: Which molecules of life are built on carbon?
Answer: Proteins, fats, carbohydrates and DNA
Life on Earth is carbon-based.

Carbon Compounds Quiz – The Element of Life

Carbon is unique because each atom can form four strong bonds, linking to other carbon atoms in chains, branches and rings. This lets carbon build millions of different compounds, more than all other elements combined.

Organic chemistry studies these compounds. They include fuels like methane and gasoline, sugars and fats in food, proteins and DNA in living cells and the plastics, medicines and dyes made in factories.

Carbon also exists in pure forms, from soft graphite in pencils to hard diamonds and the soccer-ball molecules called fullerenes. Burning carbon fuels releases carbon dioxide, linking carbon chemistry to climate change.
