A weather balloon was filled up to 7.50 L with 6.50 moles of Hy gas. The balloon gradually effuses some of its hydrogen content, deflating the balloon to 3.30 L. At this new volume, how many moles of Hy gas are there now?
A. 3.81 mol
B. 14.8 mol
C. 2.86 mol
D. 0.0677 mol

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.  

a is the answer to this question
