Which statement is true about water molecules?
grin007 [14]

Answer:

The correct answer is A. The oxygen atom has a negative charge.

Explanation:

because at the water molecule there is a covalent bond between Hydrogen atoms and Oxygen atom and in this bond the oxygen atom can attract the shared electrons more than the hydrogen atom , this result an unequal sharing of the electrons between the oxygen atom and the hydrogen atom , and this case that each molecule of water has oxygen atom with negative charge and two hydrogen atoms have positive charge

and answer D is wrong because the water called in chemistry the universal solvent , that because of its ability to solve many substance , and the substances which water cannot dissolve it is like oils and fat soluble at all

Give the structure that corresponds to the following molecular formula and H1 NMR spectrum: The proton N M R shows a triplet at
Vanyuwa [196]

Answer:

Kindly check the attached picture for the diagram of the chemical compound.

Explanation:

So, the following parameters were given from the question above;

=> A triplet at 0.9 ppm and a quartet at 1.4 ppm, a singlet at 1.35 ppm. Now, the unknown compound has a molecular formula of C7H16O.

For a triplet at 0.9ppm, there are nine (9) atoms of hydrogen, for the quartet at 1.4ppm there are six(6) atoms of hydrogen and for the singlet at 1.35 ppm, the number of hydrogen atoms is one(1). Hence, the total number of hydrogen atoms = 16.

Therefore, number of bondings = [(2 × number of carbon atoms) + 2 - number of hydrogen atoms present on the compound)/2 .

Thus number of bonds =[( 2× 7) + 2 - 16] ÷ 2 = 0.

Hence, there is no double bond or ring in the compound.
