How does the polarity of alcohol molecules change as their size increases?
As the size of alcohol molecules increases, their polarity generally decreases. This is because larger alcohol molecules have more nonpolar hydrocarbon chains that outweigh the polar hydroxyl group, reducing overall polarity.
Do hydrocarbon molecules always contain hydrogen carbon and oxygen atoms?
No.Hydrocarbon molecules contain hydrogen and carbon atoms.It is carbohydrate molecules that contain hydrogen, carbon, and oxygen atoms.
What is a molecule containing only carbon and hydrogen called?
A hydrocarbon.
Why Is Petrol Called Hydrocarbon?
Petrol is called a hydrocarbon because it is primarily composed of molecules containing hydrogen and carbon atoms. The main components of petrol are hydrocarbons such as octane, which is a chain of eight carbon atoms bonded together with hydrogen atoms.
What is the equation for cracking in crude oil?
The general equation for the cracking of crude oil involves the breaking of larger hydrocarbon molecules into smaller ones. It can be represented as: nCₓH₂y → C₍a₁₎H₍b₁₎ + C₍a₂₎H₍b₂₎ + ... + C₍aₙ₎H₍bₙ₎, where nCxHy represents a larger hydrocarbon molecule breaking down into smaller hydrocarbon molecules with different carbon (C) and hydrogen (H) compositions.
Are short hydrocarbon molecules volatile?
Yes, short hydrocarbon molecules are typically volatile because they have low molecular weights and weaker intermolecular forces, allowing them to easily evaporate into the air at room temperature. Examples of short hydrocarbon molecules include methane, ethane, and propane.
What small hydrocarbon molecules form polymers?
Monomers are small hydrocarbon molecules that form polymers.
Does longer hydrocarbon molecules have higher boiling points than short hydrocarbon molecules?
yes
What are two types of detergent molecule?
The most probable type of a molecules in the detergents is the hydrocarbon molecules and the sodium molecules. The sodium molecules binds to water while the hydrocarbon molecule binds to grease.
What is achieved in the process of cracking?
For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
What elements are present in hydrocarbon molecules?
Carbon and Hydrogen
Do short hydrocarbon molecules flow easily?
yes
How does the polarity of alcohol molecules change as their size increases?
As the size of alcohol molecules increases, their polarity generally decreases. This is because larger alcohol molecules have more nonpolar hydrocarbon chains that outweigh the polar hydroxyl group, reducing overall polarity.
Is cracking hydrocarbon molecules an endothermic or exothermic reaction?
Cracking hydrocarbon molecules is an endothermic reaction. This process requires energy input to break the chemical bonds in larger hydrocarbon molecules, resulting in smaller molecules, such as alkanes and alkenes. The energy absorbed during cracking exceeds the energy released from the formation of the new bonds in the products, making it endothermic.
Why is hydrocarbon important?
it makes smaller molecules which is more useful.
What type of reaction is cracking an example of?
Thermal Decomposition
What is The insertion of extra atoms or molecules into an unsaturated hydrocarbon?
The insertion of extra atoms or molecules into an unsaturated hydrocarbon is known as hydrocarbon functionalization. This process involves adding new functional groups to the hydrocarbon structure, increasing its reactivity and potential for further chemical reactions. It is commonly used in organic synthesis to create a wide range of compounds with desired properties.
