Which statement about hydrogen bonds is false?
(A) They have an optimal geometry.
(B) They are weak compared with covalent bonds.
(C) They cause acid-base reactions in aqueous solutions to be very rapid.
(D) They only occur between water molecules.
(A) They have an optimal geometry. (H-bonds have specific "bond angles" between the eletronegative atom and H creating a geometrical shape which is usually observed in ice)
