A compound has the empirical formula CH. A sample of this compound containing 0.387 moles has a mass of 30.19 g. What is the
molecular formula?
Select one:
O
a. C6H6
b. C2H2
0
c. C3H3
O
d. C4H4

where is the following

explanation:

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.
