It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. I need a clear answer though. Because of the weak hydrogen bonding the molecules are not close enough to maintain the liquid state of matter. Relevance. Because at atmospheric pressure the boiling point is below room temperature, just like Oxygen, Nitrogen etc. 0 7 Name the products formed when chlorine solution reacts with . Accounting . Finally there are far fewer electrons in chlorine so the van der waals forces are very week so there is sufficient energy at room temperature to break these completely and render chlorine a gas. 4 Answers. Nitrogen has a low melting and boiling point and is a gas at room temperature. Phase at Room Temperature: Gas; Density: 3.2 g/L @ 0°C; Melting Point:-101.5°C, -150.7°F; Boiling Point:-34.04°C, -29.27°F; Discovered by: Carl Wilhelm Scheele produced the gas in 1774, but it was Sir Humphry Davy who first called it an element and named it chlorine in 1810; Chlorine is the second element in the seventeenth column of the periodic table. Why is chlorine (Cl2) a gas at room temperature, but sodium chloride (NaCl) is a solid at room temperature.? Chlorine has a valency of just one and can only produce diatomic molecules Cl-Cl, also its atoms being identical makes the bond non polar which … [3 marks] Moles of chlorine = mol . Problem 108 Easy Difficulty. Chlorine has a pungent, irritating odor similar to bleach that is detectable at low concentrations. In NaCl (solid) each plane looks like a checkerboard, and then the next plane is a checkerboard offset by one square. HCl is a gas at room temperature. Dihalogens $\mathrm{X_2}$ are completely non-polar, and their intermolecular attractions are London forces that are largely proportional to molecular surface area. Lv 6.
