MCQ
What should be the correct $\text{IUPAC}$ name for diethylbromomethane?
  • A
    $1-$Bromo$-1,1-$diethylmethane
  • ✓
    $3-$Bromopentane
  • C
    $1-$Bromo$-1-$ethylpropane
  • D
    $1-$Bromopentane
✓

Answer

Correct option: B.
$3-$Bromopentane
  1. The structural formula of given compound 'diethylbromomethane' reveals that the longest chain of carbon atoms has five $C -$atoms in it, therefore the root word is 'pentane'.
  2. The substituent $'Br\ '$ is linked with the third carbon atom of the longest chain, hence the $\text{IUPAC}$ name of diethylbromomethane is $'3-$bromopentane$\ '.$
