How many constitutional isomers are possible for C4H9Br?
February 20th, 2023
I count four constitutional isomers of ##”C”_4″H”_9″Br”##.
First draw all the constitutional isomers of ##”C”_4″H”_10##. You get
(from hardinars.tk)
and
Then put a ##”Br”## atom in every possible location on each of the carbon skeletons.
From the straight-chain isomer, we get
1-Bromobutane
and
2-Bromobutane
From the branched-chain isomer, we get
1-Bromo-2-methylpropane
and
2-Bromo-2-methylpropane
And there are your four constitutional isomers of ##”C”_4″H”_9″Br”##.
