2. A deep underground cavern contains 2.24 x 106 Liters of methane gas at a pressure of 1500 kPa and a temperature of 42°C. How many grams of methane(CH.) does this gas
deposit contain?

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.  

i believe the answer is true.
