Vedclass · Answer

(A) single water molecule $(H_2O)$ consists of one oxygen atom covalently bonded to two hydrogen atoms. Therefore,there are $2$ covalent bonds within the molecule.Hydrogen bonds are intermolecular forces that occur between different water molecules,not within a single molecule. Thus,the number of hydrogen bonds within a single water molecule is $0$.Hence,the correct answer is $2, 0$.
