Question (Corrected):

Give the IUPAC name of following

$\\\tt CH_{3}-CH_{2}-CH_{2}-CH_{3}$

Answer:

Butane

Explanation:

How to name a pure hydrocarbon:

• Recognize if it is alkane (all single bonds), alkene(at least one double bond), alkyne (atleast one triple bond): Here's it's alkane so the ending will be -ane [-ene for alkene and -yne for alkyne
• Recognize the longest chain and the type : it's a straight chain of 4 carbons here so we use beut [ meth for 1 , eth for 2 , prop for three and so on]

So the final name becomes Beutane.
