What is structure of isopropyl bromide and secondary propyl bromide

[@DrBob-fp6gp]

The easiest way to answer this is with drawings. The propyl group is small and does not have a "secondary propyl" version. If you apply logic, you would put the bromide on the secondary carbon of the propyl, which would give you the same exact thing as the "isopropyl bromide". An isopropyl group is one that is connected by the secondary carbon, so it is also the secondary propyl group.
For more complicated groups, like butyl, there is more variation. Propyls can only be normal or isopropyl groups.

[@riyaroy3670]

What is diamethyle

[@DrBob-fp6gp]

Di methyl would be two methyl groups (-CH3)

[@On99123]

if you still confused you can figure it out via this link ruclips.net/video/N0o2T7DKTw8/видео.html

[@mayali666]

Could it be considered that sec-butyl and isobutyl are the same ? They seem identical

[@DrBob-fp6gp]

For the sec-butyl, all 4 carbons are in a chain, but the chain is connected to something else on a secondary carbon. For iso-butyl, the something else is connected on the end carbon, but there is a methyl branch off the chain.
