Which statements regarding shape and charge complementarity are true?

1) Charge complementarity occurs when specific noncovalent binding interactions occur between two contacting surfaces.
2) The "charge" interactions can be charge-charge, H-bonding, or van der Waals interactions.
3) Shape complementarity refers to the intimate contact made between an antibody and its target antigen.
4) Shape and charge complementarity explain exclusively the interactions between an antibody and its target antigen.

Only statements 1, 2, and 3 are true.

Answer #1

1) Charge complementarity occurs when specific noncovalent binding interactions occur between two contacting surfaces.

Reason : Charge complementarity occurs when two opposite sign are close to each other. In covalent bonds opposite charges are not present.
2) The "charge" interactions can be charge-charge, H-bonding, or van der Waals interactions.

True : the electronegative element acquire negative charge and hydrogen positive charge in hydrogen bond
3) Shape complementarity refers to the intimate contact made between an antibody and its target antigen.

Yes,   it can be defiend as interaction between biological molecules and ligand to be binded to it.
