Question

Classify the following compounds as primary, secondary, and tertiary halides.

(A) $1$-Bromobut-$2$-ene

(B) $4$-Bromopent-$2$-ene

(C) $2$-Bromo-$2$-methylpropane

Answer 1

$\text{(A)}1\text{-Bromobut-}2\text{-ene}$

In primary halides, the carbon atom bonded to the halogen atom is bonded to only one carbon atom.


$\text{(B)}4\text{-Bromopent-}2\text{-ene}$

In secondary halides, the carbon atom bonded to the halogen atom is bonded to two carbon atoms.



$\text{(C)}2\text{-Bromo-}2\text{-methylpropane}$

In tertiary halides, the carbon atom bonded to the halogen atom is bonded to three carbon atoms.
