Two statements are given below:
Statement I: Octet theory accounts for the shape of the molecules.
Statement II: Octet theory does not explain the relative stability of the molecules.
The correct answer is:
- Statement I: The octet theory primarily explains the tendency of atoms to have eight electrons in their valence shell to achieve stability. It does not directly account for the shape of molecules, which is better explained by the VSEPR (Valence Shell Electron Pair Repulsion) theory. Therefore, Statement I is not correct.
- Statement II: The octet theory does not explain the relative stability of molecules, especially in cases where molecules have expanded octets or odd-electron species.
Thus, Statement II is correct.
Final Answer: Statement-I is not correct but statement-II is correct
The correct statements about the adsorption of gas on solid adsorbent are:
Adsorption is always exothermic. Physisorption may transform into chemisorption at high temperature. Physisorption increases with increasing temperature but chemisorption decreases with increasing temperature. In physisorption enthalpy of adsorption is 100 kJ mol\(^{-1}\).
