23) All possible isomers

C2H5Br
C2H4Br2
C2H3Br3
C2H2Br4
C2HBr5
C2Br6

The ones underlined can have isomers  so 9 possibilities

39) What's the issue here? OH group will react with metallic sodium. Can't be dehydrated...Carbon attached to four others...it's saturated.
and it's empirical formula isn't CH3O

I need time for the 10th...im confused too  :P
