In experiment I you noted that:
(i) Chlorine is a gas, bromine is a liquid and iodine is a solid at 300K
(ii) Sodium chloride ionizes in water but bromine and iodine do not
(iii) Sugar dissolves in water
(iv) Iodine is soluble in hexane but sodium chloride is not
(v) Bonding is essentially ionic if $\Delta x$ is greater than 2.0
If you compare the properties of $M_2(s)$ (where M is a non metal element) and the properties of NaCl (s), which of the following statements is not true?
The Na-Cl bond and the Na-M bond are ionic
The M-M bond is covalent
The melting point of $M_2$ should be higher than that of ICl
The ionization potential of Na should be lower than that of M
Na in compounds is less electronegative than M
