The correct option is A Isobutyl bromide.
Here's why:
* Isobutyl refers to a branched alkyl group with four carbon atoms. The structure (CH₃)₂CHCH₂- matches this description.
* Bromide indicates the presence of a bromine atom (Br) attached to the carbon chain.
Let's break down why the other options are incorrect:
* B Methyl bromide: Methyl bromide has only one carbon atom (CH₃Br), not four.
* C Propyl bromide: Propyl bromide has three carbon atoms (CH₃CH₂CH₂Br), not four.
* D Butyl bromide: Butyl bromide has four carbon atoms, but it's a straight chain (CH₃CH₂CH₂CH₂Br), not branched like the given compound.


I disagree with myschool option A because it is wrong. The correct answer is D - butylbromide, pleasd make the correction. Thanks!
