The dynamic critical radius of nuclei in homogeneous nucleation () can be defined as . Consider an ice crystal nucleus of 1.23 nm radius. The melting temperature of water is 273 K, the surface tension between ice and water is 10-19J/nm2 and the enthalpy of melting is 4*10-19 J/nm3. How much undercooling (in Kelvin) is required so that water can solidify via homogeneous nucleation

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.
