The elements most likely to form more than one type of ion are thetransition metals
Answer:
The top branch-chain is a Isobutane branch. And the bottom branch chain is a Neopentane branch
It would be C, because Ionic bonds have to deal with valence electrons ( the outer shell ones)
Remember that any intersection of lines is a C, and that the number of hydrogens attached are the necessary to complet the 4 bonds.
1) CH3 - CH (OH) - CH (CH3) -CH3
2) CH3 - O - CH(CH3)-CH2 - CH3
I have used the parenthesis to indicate that the radical inside is in other branch, bonded by a single line -
