In an ice crystal,each water molecule is hydrogen bonded to _______ neighbouring molecules.

Assertion : The nearly tetrahedral arrangement of the orbitals about the oxygen atom allows each water molecules to form hydrogen bonds with as many as four neighbouring water molecules. Reason: In ice each molecule forms four hydrogen bonds as each molecule is fixed in the space.

In water each H_(2)O molecule is surrounded by y neighbouring H_(2)O molecules randomly by hydrogen bonding. Find the value of y.

Which site of tRNA molecule froms hydrogen bonds with mRNA molecule?

Which site of a t-RNA molecule hydrogen bonds to a m-RNA molecule

Strongest intermolecular hydrogen bond is present in the following molecules pairs

Assertion : Carboxylic acids of lower molecular mass are water soluble. Reason : Carboxylic acids of lower molecular mass are hydrogen bonded with molecules of water.

Which substance will form hydrogen bonds to water molecules but will not will not form hydrogen bonds with its own molecules?
