14) At which temperature can water contain the most dissolved oxygen at a pressure of 1 atmosphere?
(A) 10.°C
(C) 30.°C
(B) 20.°C
(D) 40.°C

A. 10 C

Explanation:

In cold water, intermolecular forces between oxygen and hydrogen are stronger and greater. So solubility of oxygen is higher in water with lowest temperature.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
