Answer:

2-methylebutane

Step-by-step explanation:

it is a hydrocarbon and there is a specific Rule for its nomenclature.

that is known as IUPAC naming system. According to it

  • The compound that has all single bonds name ends on ane.
  • Names according to the number of Carbons,

* For one carbon compound it is known as methane,

* For 2 ethane,

* For 3 propane

* For 4 Butane and so on.

  • select the longest chain of compound
  • Start numbering with lowest substituted position at carbon
  • branch compound name as Iso and neo as whole

So keeping in mind the compound can be named as

2-methylebutane

  • As the longest chain contain four carbon atoms so it will name as butane
  • The substitution of methyl group is on C-2

*Note: it can also named as isopantane as it is branched and have five carbons but it could not be 3-isopentane.
