Best answer: What is methane ethane propane butane pentane hexane?

What are the first six alkanes?

D. Alkanes are the simplest hydrocarbon chains. These are organic molecules that consist only of hydrogen and carbon atoms in a tree-shaped structure (acyclic or not a ring).

List the Simplest Hydrocarbons.

methane CH 4
propane C 3H 8
butane C 4H 10
pentane C 5H 12
hexane C 6H 14

What is methane ethane propane and butane?

Alkanes are saturated hydrocarbons. By saturated hydrocarbons, it means alkanes have single hydrogen and carbon atoms in their chemical formula. … Methane, propane, ethane, and butane are four alkanes. Let us learn in detail about Alkanes and their physical properties below.

What are the first 4 alkanes molecules called?

The general formula of alkanes is CnH2n+2. The first four alkanes are methane (CH4), ethane (C2H6), propane (C3H8) and butane (C4H10). The simplest alkane is the gas methane, whose molecular formula is CH4.

What comes after butane?

Number of C atoms Number of isomers Name of straight chain
4 2 n-butane
5 3 n-pentane
6 5 n-hexane
7 9 n-heptane

What are the first 3 alkenes?

IMPORTANT TO KNOW:  Is gas a natural resource yes or no?

Which is a better fuel methane or butane?

Butane is used in refrigeration, cigarette lighters, heating as LPG or liquefied petroleum gas. Methane is an energy source used for heating purposes. … Methane is a potent greenhouse gas. It can form explosive mixtures with air.

Are propane methane and butane flammable?

The definition of flammable gas is: Flammable gases are explosive when they are mixed with air or oxygen in the right proportions. Examples of flammable gases are propane, hydrogen, butane, methane, ethylene, acetylene, ammonia, ethane and silane.

What are the first 10 alkynes?

Here are the molecular formulas and names of the first ten carbon straight chain alkynes.


Name Molecular Formula
Ethyne C2H2
Propyne C3H4
1-Butyne C4H6
1-Pentyne C5H8

How do you remember the first 10 alkanes?

A good way to remember the names of organic molecules is to make up a silly mnemonic where the first letter of each word matches the first letter of the organic molecules. For example the first 10 alkanes in order are , Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane, Nonane and Decane.

Why are alkanes called paraffins?

Paraffin is a truncation of Latin ‘parum affinum’ meaning ‘less affinity’ i.e. ‘less reactivity’. Alkanes have only single bonds which are sigma covalent. … Hence, alkanes are called paraffins because they have lesser affinity towards general reagents.

What is alkyne group?

functional group properties

Molecules that contain a triple bond between two carbon atoms are known as alkynes. The triple bond is made up of one σ bond and two π bonds.
