What are some examples of alkanes?

Question

examples of any alkanes like methane? are there any more aside from that?

Answer 1

Alkanes with more than three carbon atoms can be arranged in a multiple number of ways, forming different structural isomers. An isomer is like a chemical anagram, in which the atoms of a chemical compound are arranged or joined together in a different order. The simplest isomer of an alkane is the one in which the carbon atoms are arranged in a single chain with no branches. This isomer is sometimes called the n-isomer (n for "normal", although it is not necessarily the most common). However the chain of carbon atoms may also be branched at one or more points. The number of possible isomers increases rapidly with the number of carbon atoms (sequence A000602 in OEIS). For example:

C1: 1 isomer—methane

C2: 1 isomer—ethane

C3: 1 isomer—propane

C4: 2 isomers—n-butane, isobutane

C12: 355 isomers

C32: 27,711,253,769 isomers

C60: 22,158,734,535,770,411,074,184 isomers, many of which are not stable.

In addition to these isomers, the chain of carbon atoms may form one or more loops. Such compounds are called cycloalkanes.

Answer 2

methane

ethane

propane

butane

pentane

hexane

heptane

octane

etc

Answer 3

Alkanes have structural formula

Cn H2n+1

n & 2n+1 are the subscript.

NOTE: I have used' !' for the subscript.

Methane-CH!4

Ethane-C!2H!6

Propane- C!3H!8

Butane-C!4H!10

Pentane-C!5H!12

See, its easy to name the alkanes.

Prefixes                          No. of C atoms

Meth                                  1

Eth                                      2

Prop                                    3

But(pronounced as Bute)       4

Pent                                   5

Hex                                       6

Hept                                    7

Oct                                     8

Non                                    9

dec                                    10

I hope, now u will be able to write the structural formula easily.

Rate me if u like my answer.
