Help us develop a new technology in order to separate close-boiling isomers more cost effectively

Isomers have the same molecular formula but different arrangement of its atoms. Thin layer chromatography helps in the separation of substances on a thin layer of glass with the help of the differences in the interaction between the substance and its stationary phase.

The use of micro electromechanicals can be used which would do more separation at a given time when compared to the normal process.

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.  

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
