A chemistry student needs 25.0 g of 2-ethyltoluene for an experiment. He has available 150. g of a 29.5% w/w solution of 2-ethyltoluene in carbon
tetrachloride.
Calculate the mass of solution the student should use. If there's not enough solution, press the "No solution" button.

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

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.
