A hydrocarbon of molecular weight 72gmol...

A hydrocarbon of molecular weight `72gmol^(-1)` has a 2-methyl group. What is the IUPAC name? Also drawn its bond-line structure?

Text Solution

Verified by Experts

Let the molecular formula of hydroxarbon `= C_(x)H_(y)`
Molar mass `= 72 "g mol"^(-1)` (given)
The maximum value of `x=5`
`:. 5xx12+Y(1)=72`
`Y=72-60=12`
The molecular formula `= C_(5)H_(12)`
Structural formula :
`{:(" "Ch_(3)),(" |"),(CH_(3)-CH-CH_(2)-CH_(3)),(" 2-Methylbutane"):}`
