There are numerous possible constitutional isomers of bromopentane. Specifically, the bromine atom can be attached to any of the carbon atoms (although there are only three unique possibilities because the 2 end carbons are identical). So you could have:
Then you can also have different connectivity between the carbon atoms. So pentane can either be normal pentane (5 carbons in a row), or it can be a branched structure. There are two possible branched structures for pentane: 2-methylbutane ("isopentane") and 2,2-dimethylpropane ("neopentane").
For 2-methylbutane the possibilities are:
Finally, there's only one possibility for 2,2-dimethylpropane, since the four methyl groups are equivalent and the central carbon is already bonded to four other things:
1,1-dibromobutane
1,2-dibromobutane
1,3-dibromobutane
1,4-dibromobutane
2,2-dibromobutane
2,3-dibromobutane
1,1-dibromo-2-methylpropane
1,2-dibromo-2-methylpropane
1,3-dibromo-2-methylpropane
The carbon and the hydrogen remain the same, but the bromine can be moved around to various different positions on the molecule. Bromine replaces one hydrogen atom in C5H12 to give this compound, and you get to choose various hydrogen atoms to replace.

3 different isomers exist.
They are metamers but not position isomers
Probable you think to CH2Br2, dibromomethane.
The molecular geometry of C2H2Br2 is trigonal planar.The molecular geometry of C2H2Br2 is trigonal planar.

No; all the bonds are single covalent.

These are not optical isomers they are functional group isomers a subcategory of structural isomers.
I would say no they are not isomers because methylpropyl ether has four carbons, and 3-methyl-2-butanol has five carbons.
