How do those properties of Alkanes vary as the number of carbon changes?
JeromeDelCastillofb7...
As the number of carbons increase, each additional CH2 group contributes to a fairly constant increase in the boiling point and density. The melting point is also increased but to a lesser extent.

What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
Why does viscosity go on increasing with increasing chain length of straight-chain alkanes but for isomeric alkanes viscosity increase with branching?
Viscosity increases with increasing chain length of straight-chain alkanes while that for isomeric alkanes increase with branching because of the difference in the number of rings contained within their hydrocarbons.
Why is carbon found in many things?
Organic molecules are carbon-based because of its properties, otherwise carbon is not necessarily abundant in the physical world/universe. Properties include being able to form four covalent bonds because it has the highest number of unpaired valence electrons (as do other elements), can bond to itself in an endless variety of strong carbon skeletons. Many hydrocarbons have fuel properties such as methane.
Are alkenes saturated or unsaturated?
No, they are unsaturated as they contain double bonds
What is the same and different about the structures of carbon atoms when all carbon atoms have atomic number 6 but some have mass number 12 and others have 14 as the mass number?
Carbon 12 is abundant and stable. Carbon 14 is rare and radioactive Carbon 14 has ever so slightly different chemical properties than Carbon 12 but not so much as anyone but a really particular chemist would notice.
Which compounds have the maximum possible number of hydrogen atoms on their carbon chain?
The alkanes have this feature.The entire group of alkanes has this characteristic.alkane
What alkanes are gases at room temperature?
Lower alkanes are gases. As the number of carbon increases they are liquids and even solids.
Why are alkanes saturated?
This is because they have a large number of hydrogen atoms attached to the carbon atoms
What compounds have the maximum possible number of hydrogen atoms on its carbon chain?
Alkanes have the most possible number of hydrogen atoms with respect to the carbon again.
Why are alkanes more saturated?
This is because they have a large number of hydrogen atoms attached to the carbon atoms
Which is the ratio of carbon to hydrogen in this series of hydrocarbons as the number of carbons increases?
For alkanes the general chemical formula is CnH2n+2.
What is the molecular formula for alkanes with 11 carbon atoms?
75. decane 2-methylnonane 2,2-dimethyloctane 2,3-dimethyloctane etc. ... I'm not going to list all 75.
What are the two properties of carbon which lead to the huge number of carbon compound you see around us?
hat are the two properties of carbon which lead to the huge no. of carbon compounds we see around us ??
What can be said about the relationship between the number of hydrogen atoms and the number of carbon atoms in an alkane?
Yes: Alkenes follow the general formula: CnH2n (n being the number of carbon atoms in the chain), so in Alkenes, there will be twice as many H atoms than C atoms. Alkanes: CnH2n+2 Alkenes:CnH2n Alkynes:CnH2n-2
Which quantity represents the prefix used in naming straight-chain alkanes with the exception of methane propane and butane?
The quantity that represents the prefix used in naming straight-chain alkanes is the number of carbon atoms in the alkane. The exceptions to this include methane, propane and butane.
Why is propane considered a saturated hydrocarbon?
Propane is an alkane and as such, contains only single covalent bonds, so it is considered saturated because each of its carbon atoms is single bonded with a hydrogen atom or another carbon atom.
What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
