This is an enzyme protein showing two of the interactions which hold the polypeptide chain together to give its characteristic higher-order structure.Give the full correct name of the interaction.

Hydrophobic interaction & hydrogen bond for the last interaction. All weak interactions

Actually I think the top one is ionic interaction and the bottom, hydrophobic interaction

Nope, those two answers are wrong...

Where you see a hydrogen atom covalently bonded to either N, O or F, you have to look out for any possible hydrogen bonding. The hydrogen atom acquires a partial positive charge and will form a hydrogen bond with an atom with a partial negative charge, including N, O or F.

Now, when you see charges being clearly shown, that means there is an ionic bond somewhere.

Well, if with those you can't get the answer, I don't know how to help you without giving those very obvious hints. :)

The top interaction: -O-H...NH2R is a HYDROGEN BOND (a classic one)
The lower interaction: -COO- ... +H3N- is an IONIC ATTRACTION (isn't it obvious?)
Hydrophobic interactions are hydrocarbon groupa (aliphatic or aromatic) with each other.
