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.

No; all the bonds are single covalent.
Probable you think to CH2Br2, dibromomethane.
C3H12 can have two different isomers: n-propane, which is a straight chain molecule, and isobutane, which is a branched molecule.
Yes, 2-pentanone and 3-pentanone are isomers. They have the same molecular formula (C5H10O) but differ in the position of the carbonyl group (C=O) along the pentane chain.
The molecular geometry of C2H2Br2 is trigonal planar.The molecular geometry of C2H2Br2 is trigonal planar.

Diacetylferrocene can have three possible isomers: symmetrical cis-diacetylferrocene, symmetrical trans-diacetylferrocene, and unsymmetrical diacetylferrocene.
Yes, 2-pentanone and 3-pentanone are isomers. They have the same molecular formula (C5H10O) but differ in the position of the carbonyl group (C=O) along the pentane chain.

No; all the bonds are single covalent.
Compounds that do not exhibit isomerism are typically symmetrical in structure, such as molecular formula C2H6. Symmetrical compounds have identical arrangements of atoms, preventing the formation of isomers.
Tartaric acid has three stereoisomers: meso-tartaric acid and the two enantiomers, D-tartaric acid and L-tartaric acid.
CH3CH2COOH and CH3CHOHCHO have chiral centers, which are carbon atoms bonded to four distinct groups. Their mirror images are non-superimposable. This asymmetry results in optical isomerism, where the molecules exist as enantiomers.
I would say no they are not isomers because methylpropyl ether has four carbons, and 3-methyl-2-butanol has five carbons.
