Probable you think to CH2Br2, dibromomethane.
Functional group isomerism, as 1,2-butadiene and cyclobutene are its isomer, 1-butyne is its positional isomer.
No; all the bonds are single covalent.
trans isomers
It should be trigonal planar, and each carbon is sp2 hybridized.
NO
The molecular geometry of C2H2Br2 is trigonal planar.The molecular geometry of C2H2Br2 is trigonal planar.

No; all the bonds are single covalent.
trans isomers
No. CaCl2 is neither ans isomer, nor does it have isomers.
It should be trigonal planar, and each carbon is sp2 hybridized.
Yes it is. It's structural isomer is ethanol C2H5OH
no
NO
No, it is NOT either both. Besides 'benzenepropanol' is not an official name.
If you mean what is an isomer then it is a compound with the same chemical formula but with a different structure
