Solution: 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.

Problem

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.

Solution

(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)
